ALPHA S3: construction and applications

ALPHA S3 coil zipper: 25 ±1 mm tape width and 4.2 mm chain width. Lightweight fabric products; the end configuration determines suitability for garments, bags or covers. The 2018 standard slider reference is 118. Tape colour, slider and end configuration are separate ordering parameters.

Selecting the required execution

Tape width is the full textile width, while coil or tooth width refers to the closed chain. Specify the model, length, end configuration, tape colour and slider code. Equal nominal size does not guarantee slider compatibility between different series.

Colours and configuration availability

Select from the ALPHA colour card and a physical tape sample. The general manufacturer palette does not establish availability of every shade for every model. The 2018 catalogue data is identified by source date. Current website puller lists may differ; a manager will confirm the required combination. Select the shade using a physical sample, not a screen image alone.

Family decoration options

The coil family includes decorative silver, gold, dark nickel and rose-gold coil finishes; these are not automatically part of the standard execution.

Pullers and custom decoration

The catalogue describes laser engraving on CNK, SCN, OKS, PAT, NFR, MOS and MBL finishes, pad printing on plastic and metal, raised or recessed cast logos, plastic shapes 301/305/350 and flexible gel pullers. NOMEKS and SATYNA tapes are also shown at family level, without blanket model compatibility. Confirm compatibility, quantities and availability; the NOMEKS name alone does not certify the finished product as flame resistant.

Product illustration

The prepared image is based on an ALPHA manufacturer reference and illustrates the coil and tape structure. It is not a photograph of a specific batch; confirm colour and configuration against a sample.
