US Patent No. 4,913,385

• Nylon fasteners are Assembly Friendly! Independent of insertion into the chassis, Lockit Nylon Strain Reliefs self-lock onto the cable.  Thus, they may be pre-assembled off-line for final nylon fastener assembly at a later time or remote location, for a lower installed cost!
• Lockit SRs hold so well they pass the UL pull-out test requirement with or without chassis support.
• Nylon fasteners protect the lifeline of your electric/electronic products by absorbing the forces of push and pull that may be exerted on the flexible power cord.  Their rectangular design eliminates the possibility of part rotation under forces of twist!
• Lockits' three finger design securely anchors into chassis.  Five locking steps and a slim head profile make Lockits design-specific!
• Molded of type 6/6 nylon.  ASTM D-4066; flammability classification 94V-2; temperature index 125°C. Maximum temperature on the part shall not exceed 105°C.
