Structure & Working Principle
NRH 5401-122 relies on pure mechanical interlocking for ultimate safety, composed of three core coordinated parts:
-
Fixed Strike Plate: Thickened steel base with three reinforced mounting points, evenly bearing huge shear force and tensile force, solid and not easy to deform.
-
90° Forged Hook: Precision integral forging optimizes metal grain structure, eliminates weak points, and greatly improves bending resistance and anti-prying performance.
-
Heavy-Duty Rotating Bail: U-shaped thickened locking bar precisely matches the hook size. After closing, the 90° limit structure prevents vertical lifting and forms a stable mechanical anti-theft lock.
Two-step manual closing brings clear operation feedback and reliable physical protection. No spring design adapts to extreme temperature changes, avoiding aging, fatigue and jamming, and maintaining long-term stable service life.
