Lay-In Strain Relief fasteners self-lock onto the cable to make assembly easy! Thus, the fasteners may be pre-assembled off-line for final assembly at a later time or remote location, for lower installation cost.
Each Lay-In strain relief is designed to be installed in split chassis mounting hole or dropped into a slot. (see schematic)
Unique wire locking ratchet on these strain reliefs allows for generous wire range from .250"(6,4mm) to .600"(15,2mm).
The strain reliefs protect against forces of pull, push or twist.
Molded of type 6/6 nylon. ASTM D-40660; flammability classification 94V-2; temperature index 125°C.
Can be used to fasten one cable or bundles of cables (round or flat wire).
