Heyco 3171 Strain Relief 18-22g

The Heyco 3171 strain relief is a durable SR‑series bushing engineered for 18–12 AWG cable, providing secure cord retention and protection against pull‑out in panels, appliances, lighting fixtures, and OEM harness assemblies. Its molded nylon construction resists flexing, vibration, and mechanical stress, while the split‑body design grips the cable firmly without damaging insulation. Designed for fast, reliable installation into a matching panel hole, this strain relief maintains stable performance in demanding electrical environments.
