What Is a Closed-End Zipper?
A closed-end zipper has a bottom stop that keeps both zipper tapes joined when the slider reaches the lower end. The chain opens, but the left and right tapes do not separate completely.
Closed-end zippers are also called bottom-stop zippers. The bottom stop prevents the slider from leaving the chain and defines the lower end of the closure.
Closed-end does not mean waterproof, airtight or permanently sealed.
Selection by Application
| Application | General Zipper Approach | Important Check |
|---|---|---|
| Wallet, coin purse and inner pocket | 10–18 cm / 3.94–7.09 in #3 nylon coil zipper | Measure the real opening and confirm slider direction. |
| Trousers, shorts and skirts | 14–25 cm / 5.51–9.84 in nylon or genuine metal zipper | Measure the fly, side seam or back opening from the pattern. |
| Jacket and coat pocket | 14–24 cm / 5.51–9.45 in #5 coil, molded or coated zipper | Test fabric bulk, pocket opening and pull-tab access. |
| Dress, formalwear and bridalwear | 16–60 cm / 6.30–23.62 in invisible zipper | Check the dressing opening, fabric layers and tape construction. |
| Bag, pouch and organiser | Ready-length or workshop-finished continuous chain | Test curves, one- or two-slider operation and end finishing. |
| Cushion, cover and home textile | Nylon coil or invisible closed-end zipper | Provide enough opening to remove the filling or inner component. |
| Outdoor bag and technical pocket | Coated closed-end zipper | Test coating, stitch holes, slider junction and zipper ends. |
Closed-End and Open-End Zippers
| Feature | Closed-End | Open-End Separating |
|---|---|---|
| Bottom construction | The tapes remain joined at a bottom stop. | The tapes detach through an insertion pin and retainer box. |
| Typical use | Pockets, trousers, skirts, dresses, bags and cushions | Jackets, coats, vests and full-length outerwear |
| Complete tape separation | No | Yes |
Single-Slider and Dual-Slider Closed-End Zippers
Single-slider closed-end zippers are widely used for trousers, pockets, wallets, dresses, cushions and small bags.
Some bags, luggage items and equipment cases use two separate sliders on one closed-end chain.
A dual-slider closed-end bag zipper is not a two-way separating or combi zipper. A combi zipper is an open-end outerwear construction with two sliders and lower-opening operation.
A slider with two pull tabs is also not the same as two separate slider bodies.
Nylon Coil Closed-End Zippers
Nylon coil zippers use a continuous spiral chain and can provide a flexible closure for wallets, bags, pockets, trousers, skirts, cushions and cases.
Verified Turkish Type 5 coil products should use #3 in English product naming, while verified Turkish Type 10 products should use #5.

Invisible Closed-End Zippers
An invisible zipper is a specialised closed-end nylon coil zipper whose chain folds behind the tape and remains concealed inside a garment seam.
It is used for dresses, skirts, bridalwear, formalwear and women's trousers where minimum exterior visibility is required.
See available lengths in the invisible zipper category.
Molded Plastic Closed-End Zippers
Molded plastic zippers use individual plastic teeth attached to textile tape. They may be selected for jacket pockets, bags, accessories and visible fashion closures.
Standard, crocodile-tooth and metallic-look molded teeth remain plastic constructions.
The Turkish term “bone zipper” does not mean natural bone.
Genuine Metal Closed-End Zippers
Genuine metal-tooth closed-end zippers may be used for jeans, trousers, skirts, leather products, pockets and decorative bags.
The base alloy and the visible finish should be listed separately. Metallic-look nylon or molded teeth are not genuine metal chain.
Coated Closed-End Zippers
TPU- or PU-coated closed-end zippers may help reduce surface moisture entering through technical pockets, outdoor bags, footwear and equipment cases.
A coated zipper alone does not make the finished product fully waterproof. Stitching, slider gaps, the bottom stop, zipper ends, fabric and installation also affect protection.
See related products in the coated zipper category.
Ready-Length and Continuous Chain
A ready-length closed-end zipper includes a defined functional length, installed slider and completed bottom stop.
Continuous zipper chain is cut during production and still requires compatible sliders and secure top and bottom finishing.
Continuous chain is not automatically a finished closed-end zipper.
Browse workshop chain in the continuous zipper-chain category.
How Is Closed-End Zipper Length Measured?
Measure the functional chain from the top stop to the bottom stop. Do not include additional zipper tape above or below the working chain.
Replacement selection should also match the chain material, zipper size, tape width, slider and bottom-stop construction.
Common Selection and Product-Data Errors
- Do not describe the bottom as capped, airtight or sealed.
- Do not classify every closed-end zipper as nylon.
- Do not describe a dual-slider closed-end bag zipper as combi.
- Do not confuse one double-pull slider with two slider bodies.
- Do not classify metallic-look nylon or plastic as genuine metal.
- Do not claim full waterproofing from a coated zipper alone.
- Do not treat continuous chain as a finished zipper.
- Do not approve replacement compatibility from length alone.
Frequently Asked Questions
What is a closed-end zipper?
A closed-end zipper keeps both tapes joined at a bottom stop, so the tapes do not detach when the zipper is fully opened.
Are closed-end and bottom-stop zippers the same?
Yes. Bottom-stop zipper describes a closed-end zipper with a fixed lower stop that keeps both tapes joined.
Where are closed-end zippers used?
They are used for pockets, wallets, bags, trousers, skirts, dresses, cushions, cases and organisers.
Is a dual-slider closed-end zipper a combi zipper?
No. A dual-slider closed-end bag or luggage zipper is not combi. A combi zipper is an open-end, two-slider outerwear zipper with lower-opening operation.
Can continuous zipper chain be made closed-end?
Yes. After cutting, compatible sliders must be installed and the top and bottom ends must be finished securely for the intended load.
How is closed-end zipper length measured?
Measure the functional chain from the top stop to the bottom stop. Do not include additional tape left for sewing.
Is a coated closed-end zipper completely waterproof?
Not by itself. Stitching, slider gaps, the bottom stop, zipper ends, fabric and installation affect the finished protection level.
