When it may not be suitable
This lock nut is specifically designed for use with metric SKINTOP plastic cable glands and may not be compatible with non-metric or metal-specific cable gland systems. It is not intended for high-temperature environments that exceed the thermal limits of polyamide materials.
Key specifications

How to use
To install, place the lock nut onto the threaded portion of the cable gland after it has been inserted through the borehole.

Ensure that the cable gland is properly aligned before final tightening to prevent cross-threading. When used in conjunction with UL-approved plastic cable glands, the assembly maintains its certified performance standards.
