Description

These twist-on wire caps ensure a secure, reliable connection for all standard electrical and low-voltage applications. Engineered with a durable steel core and a UL94V-2 flame-retardant thermoplastic shell, they feature an internal spring design that grips wires tightly for a superior, long-lasting hold.

Active Spring-Action Grip

An internal steel spring design actively bites into stripped wires as you twist, ensuring a highly secure connection that won't loosen under mechanical vibration or thermal expansion.

High-Heat & Flame Resistance

Encased in a rugged thermoplastic cover with a UL94V-2 flame rating, safely handling operating temperatures up to 105°C (221°F).

Fully Certified & Compliant

Meet safety and environmental standards, carrying UL, CSA, and RoHS certifications for peace of mind on regulated job sites.
