Two-Way Separating Zipper Sourcing Program for Airlines and Rail Operators: Socks
Two-Way Separating Zipper Programme for Airlines and Rail Operators: Socks
This programme covers the full path from a two-way separating zipper requirement to a repeatable bulk supply for airlines and rail operators. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 8# Gauge, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around socks, which is where most of the specification detail sits.
The most common failure in two-way separating zipper sourcing is not price — it is drift. A base material changes mill, the shade moves, a plating bath changes and the item quietly stops matching the approved sample. We prevent that with a written spec, an approved counter sample and a golden sample retained at the factory.
What the programme covers
- Specification build from your tech pack or a physical reference sample
- Base material and finish options with costed alternatives
- Sampling, testing and approval against California Prop 65
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- PU Leather — selected for colour depth and finish stability
- Copper — chosen when the item has to survive repeated laundering
- Acrylic — selected for colour depth and finish stability
- Stainless Steel — best balance of cost, availability and test performance

FAQ
Can you handle our own artwork or tooling?
Yes. Artwork files or existing tooling can be used; we confirm tolerances in writing before the first production run.
Do you hold stock for reorders?
Approved specifications are kept on file and, for repeat programmes, base material can be reserved against a rolling forecast.
How long does sampling take?
14 working days for the first sample, with 5 days per revision round. Plated or dyed-to-match items add a few days.
What is the minimum order quantity?
Standard MOQ is 3000 per style per colour. Mixed colourways can be combined on the same spec if the base material is identical.
If you are comparing suppliers, send us the spec they quoted against. We will quote the same spec and show you where the difference sits.
