Toothed zippers consist of individual molded Delrin® 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. 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 inch and larger and on flat ribbon cables over 2.0" wide. Toothed zippers can be used in very large size applications by increasing the tooth size. Ideally all zippers should be used in applications that are free of dirt and debris which could cause jamming, however toothed zippers are easily cleaned with a small brush if contaminated. For smaller cables and lightweight applications use a "coil zipper" style. 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.
