N3 / #3 Single-Pull Nylon Zipper Slider – Nickel Zamak KRSTT5

For made-to-length #3 nylon zipper projects

When a pouch, bag, case or organizer does not use a standard ready-made zipper length, continuous zipper chain can be cut around the actual opening. This N3 / #3 single-pull slider is the moving component that closes and opens compatible nylon zipper chain in those custom zipper runs.

It is a useful choice for repair shops, sewing studios, small-batch bag makers and DIY projects where the zipper is normally accessed from one exterior side. The slider is not a complete closure by itself; it must be paired with compatible chain and properly finished at both ends.

Choose the pull-tab arrangement for the way the product is used

A single-pull slider has one pull tab on one side of the slider body. It can suit pencil cases, document pouches, small organizers, bag openings and textile covers where one main access side is enough.

Products that need easy access from both sides may require a double-sided slider instead. The correct choice is based on the user’s handling position, product orientation and the direction the zipper needs to open after sewing.

Check zipper-chain compatibility before a repair or production run

Even when a zipper is described by the same size family, differences in coil shape, tape profile, tooth construction and slider channel can affect fit. Use the exact nylon chain intended for the project and test one slider on a short sample before cutting multiple zipper lengths.

The slider should move smoothly, close the chain evenly and leave no open section behind it. If there is resistance, uneven closing or a visible gap, stop before sewing the zipper into the finished item and recheck the chain-slider match.

Suitable applications

With compatible #3 nylon zipper chain, this slider can be used for pouches, cases, cosmetic bags, organizers, inner compartments, textile covers and smaller repair projects. The final application should be selected according to fabric thickness, lining bulk, zipper channel width and expected opening frequency.

For a larger, heavier or more frequently used opening, a different zipper size may be more appropriate. Do not select the slider by color alone; zipper structure and product use should always guide the decision.

Nickel-color zamak construction

The nickel-color finish can coordinate with many bag fittings, rings, hooks and buckles. Zamak zinc alloy is used for the slider body, but finished zipper performance also depends on correct sewing, parallel zipper-tape placement and enough clearance around lining and edge binding.

After installation, both ends of the zipper chain should be finished so the slider remains inside the intended zipper path. This is particularly important when preparing custom-length zipper runs from continuous chain.

Before installation

• Confirm that the zipper chain is compatible N3 / #3 nylon chain.
• Test the slider on a short sample before cutting the final zipper length.
• Check that both tape sides enter the slider evenly.
• Choose the intended opening direction before sewing.
• Finish both chain ends to prevent the slider from leaving the zipper run.

Custom slider requests

For custom zipper hardware, provide the zipper size, desired finish, pull-tab configuration, intended product type, estimated quantity and any logo, drawing or physical sample. This helps match the slider construction to the finished bag, case or textile product.

Frequently Asked Questions

Is the zipper chain included?

No. This product is a zipper slider only. Compatible N3 / #3 nylon zipper chain should be selected separately.

Can I use this for a pouch or bag repair?

It may be suitable when the existing zipper chain matches in size and profile. Test the slider on a short section before completing the repair.

What does single pull mean?

It means the pull tab is located on one side of the slider body. It does not mean the zipper only moves in one direction.

Is this a double-sided zipper slider?

No. This is a single-pull slider. A double-sided model is more suitable when the zipper must be operated from both faces.

What material is the slider made from?

The slider body is made from zamak zinc alloy.

What is the minimum purchase quantity?

The minimum purchase quantity is 20 pieces.
