Mechanical Chain Zipper
- Mechanical, seperating brass zipper
- Molded Tooth design, 4.5-10mm sizes
- Ideal in high strength & flexure applications
Brass toothed zippers consist of individual brass metal interlocking teeth attached to a separating Polyester fabric tape which has a fixed start and stop point. The zipper is closed via a self-locking slider which make a zipper installation tool free. Brass toothed zippers are available as a medium or heavyweight, highly flexible, closure system for cables where a tool-free installation is desired and the open/closure cycle frequency is likely to be high. Toothed zippers perform best in round cable applications where the cable bundle diameters exceeds 1.0" and larger and on flat ribbon cables over 2.0" wide. Brass toothed zippers can be used in very large size applications by increasing the tooth size. Brass toothed zippers are stronger than molded toothed zippers and more immune to damage. However, unlike plastic zippers they do not have a "self-lubricating" quality and may require periodic lubrication to operate smoothly. Ideally all zippers should be used in applications that are free of dirt and debris which could cause jamming. Brass zippers can be cleaned with a small brush if contaminated and they are prone to corrosion unlike plastic zippers. Zippers cannot be cut to length on site at the time of installation so assembly length must be known at the time of order. Zippers items are typically commercial items and meet the manufactures performance specification; however they can be procured in compliance to A-A-55634.
