2-Hole Metal Spring Cord Lock DG-CL028

Quick Answer: What Is a 2-Hole Metal Spring Cord Lock?

A 2-Hole Metal Spring Cord Lock is a spring-loaded drawstring adjustment component designed to hold two cord ends at a chosen position. This zinc alloy version uses a pressable top button and an internal compression spring: press the button to release the cord, slide the stopper to adjust drawstring length, then release it to lock the cord in place. It is commonly used on hoodies, jackets, coats, sportswear, waist drawcords, hats, bags and outdoor accessories. The bright nickel-plated finish gives the component a clean metal appearance, while the double-hole structure suits paired drawcords. For OEM buyers, the important checks are actual cord diameter, spring holding force, edge smoothness, plating consistency and the intended wear environment.

Key Takeaways for Garment and Accessory Buyers

• The double-hole structure is designed for two drawcord ends, not for terminating a single cord.
• The internal compression spring controls both release feel and cord-holding performance.
• Approximate 5.5 mm cord passages require testing with the actual cord material and compressed diameter.
• Zinc Alloy supports die-cast shape development, polished surfaces and multiple electroplating finishes.
• Bright nickel is suitable for silver-tone fashion hardware but requires careful storage to reduce scratching.
• This component is functional garment hardware, not a load-bearing buckle or safety-rated connector.
• OEM options can include size, shape, spring force, plating color, logo and private-label packaging.

How the Double Hole Cord Lock Mechanism Works

A Double Hole Cord Lock works by applying spring-controlled pressure to the drawcord after it has passed through the housing. The user presses the upper button, which compresses the internal spring and opens the cord path enough for adjustment. Once the button is released, the spring returns the mechanism to its locking position and creates resistance against cord movement.

This operating principle sounds simple, but the user experience depends on several dimensions working together. The button travel must be enough to let the cord slide without excessive force. The spring must provide reliable retention without making the cord lock difficult to press. The two cord channels also need to remain aligned, otherwise one cord may move more freely than the other.

For garment brands, a Metal Drawstring Cord Stopper should be evaluated with the actual drawcord rather than only with a nominal diameter. A soft round cord, flat woven tape, elastic cord and tightly braided polyester cord can behave very differently inside the same hole size. During prototype development, we recommend testing repeated pressing, sliding, locking and washing-related handling before approving bulk production.

Quick Knowledge for Selecting a Spring Cord Lock

What is the difference between a cord lock and a cord end?

A cord lock adjusts and holds a drawstring at a selected length. A cord end, also called an aglet or cord tip, finishes the end of a cord and helps prevent fraying. This product is a Spring Toggle Cord Lock because its role is adjustment and retention, not end finishing.

Why does cord compression matter more than nominal cord size?

A cord marked as 5 mm may compress significantly when pressed through a stopper, while a stiff braided cord with the same nominal diameter may not pass smoothly. Buyers should check the cord’s real cross-section, yarn density, coating and compression behavior. A 5.5 mm opening is a useful reference, but it does not replace physical fitting tests.

Metal Cord Lock vs Plastic Cord Lock

Zinc Alloy Body and Bright Nickel Finish

This Zinc Alloy Cord Lock is suitable for die-cast production because the material can reproduce a compact three-dimensional housing with rounded contours, cord passages and button details. After casting, the part typically goes through trimming, grinding and polishing before electroplating. Each step affects the final appearance, especially on a bright nickel finish where surface imperfections are easier to see.

Bright nickel creates a clean silver-tone appearance for hoodies, jackets, bags and fashion accessories. It is important to distinguish visual finish from performance claims. Nickel plating may improve appearance and provide surface protection, but corrosion resistance depends on the complete plating system, polishing preparation, coating thickness, base material condition, sealing process, storage and end-use exposure. Salt Spray Testing requirements should therefore be agreed before production if the product will be used in humid, coastal or outdoor conditions.

For collections requiring a different look, the same basic 2-Hole Metal Spring Cord Lock design can be developed in gunmetal, black nickel, matte black, antique brass, antique silver, gold-tone or other approved finish options. Samples should be compared under the intended lighting because plated color can look different in a factory, retail store and product photography.

Dimensions That Affect Cord-Lock Performance

The supplied drawing indicates an approximate overall height of 27.7 mm, a top-button width of 10 mm, a body width of 9.3 mm, an internal cord opening reference of 5.5 mm and an approximate unit weight of 6.6 g. These values are useful for preliminary product development, but buyers should confirm final production dimensions with a technical drawing and physical sample.

Where a Metal Drawstring Cord Stopper Is Used

A Metal Drawstring Cord Stopper is commonly used where two cord ends need adjustable tension or a controlled gathered shape. On hoodies and jackets, it can secure a hood opening or hem drawcord. On waistbands, it can help adjust fit without a conventional buckle. On bags and pouches, it can control an opening while adding a matching metal-trim detail.

One development situation we often see is a brand moving from a standard black plastic stopper to a nickel-plated metal part for a fashion jacket. The visual upgrade is straightforward, but the project needs more than a color change. The metal part adds weight, the cord may need a different diameter, and a glossy plated surface can make scratches more visible during factory assembly and transportation. The practical solution is to confirm cord fit early, define acceptable cosmetic standards, and use suitable separation packaging before the production run.

• Hood drawstrings on hoodies, windbreakers and casual jackets.
• Hem adjustment cords on coats, parkas and outdoor apparel.
• Waist drawcord systems on joggers, shorts and performance clothing.
• Drawstring bags, cosmetic pouches and lightweight travel organizers.
• Caps, hats and headwear with adjustable retention cords.
• Shoes, footwear bags and selected shoelace-adjustment accessories.
• Outdoor equipment covers and compact storage bags, subject to application testing.

Manufacturing Process: From Die Casting to Cord-Lock Assembly

For a zinc alloy spring cord lock, consistent production begins with the die-cast housing. Molten Zinc Alloy is injected into a precision mold to create the outer body and button geometry. The casting is trimmed to remove gates and excess material, then ground and polished so visible surfaces and cord-entry areas become smoother before electroplating.

After the surface preparation stage, the internal compression spring and moving button components are assembled. This is where alignment matters: an off-center spring or inconsistent assembly position can change button travel and cord-holding feel. The assembled parts then move through electroplating according to the approved finish standard. For bright nickel, surface cleanliness before plating is particularly important because polishing marks, pits or die-casting irregularities can become more noticeable after the reflective finish is applied.

QC Inspection should include appearance checks, cord threading checks, button press testing, sliding performance, locking consistency, assembly integrity and packing verification. When customers require corrosion-related performance, Salt Spray Testing parameters should be specified in the purchase requirement instead of assumed from the finish name alone.

Factory Expert Tips for Choosing a Double Hole Drawstring Toggle

• Send the actual cord, not only the cord diameter. A physical cord sample shows compression, surface friction and threading behavior that drawings cannot fully predict.
• Define the preferred button feel before mass production. A loose press may feel convenient but can reduce holding force; an overly strong spring can frustrate end users.
• Use rounded and polished cord-entry edges when selecting braided polyester, elastic or coated drawcords. This helps reduce abrasion during repeated adjustment.
• Choose bright nickel only after considering handling marks. For rugged outdoor goods, matte finishes or darker electroplating may hide minor surface scuffs better.
• Confirm if the item will be assembled before or after garment washing. Washing, tumbling, moisture and chemical exposure can affect the finish and spring-related performance.
• For custom logos, consider whether the available visible surface is large enough. A small cord lock may suit a subtle embossed symbol better than a detailed multi-character mark.

Common Buying Mistakes

• Choosing a cord lock only by its exterior size without testing it with the intended drawcord.
• Assuming a 5.5 mm opening fits every cord labeled 5 mm.
• Ignoring spring force and focusing only on plating color.
• Using a glossy nickel-plated item without defining scratch-control packaging.
• Calling a metal finish corrosion-proof without agreeing on actual test conditions and acceptance criteria.
• Using a functional cord stopper as if it were a load-bearing connection component.
• Approving a sample without checking whether both cord ends slide and lock consistently.
• Changing drawcord material after hardware approval without repeating the fit and retention test.

Buyer Decision Guide: Is This Cord Lock Suitable for Your Project?

OEM Customization for Zinc Alloy Cord Locks

DG Buddy can support OEM and ODM development for drawstring hardware projects. A standard shape is usually the fastest route when the buyer needs an existing metal cord stopper with a specified plating color and packing method. A Custom Mold may be appropriate when a collection requires a unique silhouette, larger button, revised cord-hole size, different spring action or visual consistency with other branded hardware.

Customization can include zinc alloy body shape, top-button profile, hole diameter, spacing between the two cord channels, spring force, bright nickel or alternative Electroplating, laser logo, embossed logo, debossed logo, oil filling, private-label packaging, barcode labels, hang tags and retail boxes. The final approach should be based on the size of the visible logo area and the product’s required production volume.

Before tooling begins, it is helpful to provide a 2D drawing, 3D file, physical reference sample, target cord sample, finish swatch, artwork and packaging requirement. If these are not available, our project team can review the intended application and identify the dimensions that need to be fixed before sampling.

Care, Storage and Handling Advice

Bright nickel-plated drawstring hardware should be stored in a dry environment and protected from prolonged contact with moisture, perspiration, acidic substances, aggressive detergents and abrasive materials. The finish can be affected by humid warehouses, wet garment handling or contact between unprotected metal parts during transport.

For bulk handling, parts should be separated with suitable protective packaging rather than shipped loose against each other. Pearl foam, OPP bags and export cartons help reduce contact marks during transportation. For cleaning, use a soft dry cloth where appropriate; do not use abrasive pads or unapproved chemical cleaners that may dull the electroplated surface.

Frequently Asked Questions

What cord size fits this 2-Hole Metal Spring Cord Lock?

The drawing shows an approximate 5.5 mm cord opening reference, but the correct cord size must be confirmed with physical samples. Actual fit depends on the cord’s shape, yarn density, coating, softness and how much it compresses. A round polyester drawcord and a flat woven cord with the same nominal measurement may behave differently. We recommend sending the intended cord for threading, sliding and locking tests before bulk approval.

Is the body made from zinc alloy or brass?

The stated body material is Zinc Alloy. Zinc alloy is commonly used for compact die-cast garment hardware because it can create detailed shapes and accepts polishing and electroplating finishes. The internal spring is a separate functional component. If your project requires brass, stainless steel or another specified material, please share the drawing or application requirement for evaluation.

Can the spring force be customized?

Spring force may be adjusted during OEM development, subject to the product structure, target cord and button-travel requirements. A stronger spring can improve retention but may increase press force. A softer spring can improve operating comfort but may allow the cord to slip more easily. The best setting is normally established through sample testing with the intended drawstring.

Can you make this cord lock in matte black, gunmetal or gold?

Yes. Besides the bright nickel finish shown, finish options can be evaluated for gunmetal, black nickel, matte black, antique brass, antique silver, gold-tone and other approved color directions. Final color should be confirmed against an approved sample or finish standard. Plated appearance can vary with base polishing, coating process and lighting conditions.

Can you add our logo to the metal cord stopper?

OEM logo options may include laser marking, embossed logo, debossed logo and oil filling, depending on the available area and design detail. Because a compact Double Hole Drawstring Toggle has limited visible surface, simple symbols and short marks usually reproduce more clearly than detailed artwork. Please provide vector artwork and the preferred logo position for evaluation.

What is the MOQ for this product?

The MOQ for this individual hardware product is 1000 pcs, negotiable based on order details. MOQ may be influenced by the requested plating finish, custom mold requirement, logo process, packaging method and whether the order uses a standard or newly developed structure. Share your estimated quantity and specification so we can recommend the most practical production route.

Can I request a sample before placing a bulk order?

Free stock samples available. Custom samples require a sampling fee. Custom sample fees are fully deductible from bulk orders. Courier charges are borne by the customer. For a custom spring cord lock, the sample stage is where buyers should confirm cord compatibility, press feel, plating color, logo clarity and cosmetic acceptance criteria before bulk production.

Do you provide certification or compliance documents?

We maintain quality certification documentation and are happy to provide the current valid certificates upon request during your sourcing evaluation. Requirements differ by product material, finish, destination market and customer standard, so please identify the specific documentation or test requirement you need before quotation and production approval.

What are the production and delivery times?

Sample Time is 5–7 Days for custom development. Production Time is 10–15 Days, and Delivery Time is 10–15 Days. Actual scheduling can change according to order quantity, plating process, custom tooling, packing requirements and production capacity at the time of order confirmation. A final delivery plan should be confirmed with the approved sample and purchase order.
