The NRH R7956-12-220 Spring Pin Latch is a heavy-duty industrial grade fastening component. Precision crafted from premium 304 stainless steel with vibratory polished finish, it delivers outstanding structural strength and superior all-weather corrosion resistance, with a solid net weight of 445g for stable heavy-load performance. As a core model of the NRH 79 Series, it inherits mature vibration-proof locking structure and rapid assembly design. Equipped with 12mm thick pin diameter and 220mm overall length, it supports tool-free one-handed operation, perfectly suitable for locking heavy access panels, machine safety guards and large industrial enclosures.
Adopting professional spring built-in mechanism and over-center self-locking principle, the latch stays firmly locked under strong shock and vibration, avoiding accidental popping open. Standardized overall size and reserved installation structure match mainstream industrial equipment panels, realizing fast positioning and efficient assembly.
