Gibraltar LBL-150 Quick-release Pin 0.5 in 4.5 in 4130 Steel

Product Description

The GIBRALTAR LBL-150 is a quick-release pin with an L-handle, designed for fast, tool-free removal in mechanical assemblies, jigs, fixtures, and structural connections. The pin measures 0.5 inches in diameter with a 4.5-inch usable length, providing a solid grip surface and reliable retention in through-hole applications. Constructed from 4130 alloy steel with a zinc-plated finish, the LBL-150 resists corrosion and handles moderate mechanical loads. Machinists, fabricators, maintenance technicians, and industrial assembly workers are the typical installers of this type of fastener hardware.

This quick-release pin is suited for use in light to medium-duty industrial, agricultural, and mechanical applications where frequent disassembly is required. The L-handle configuration allows for hand-tightened insertion and one-motion pull release without tools. Typical use cases include pin joints, hinge connections, removable guards, tooling plates, and equipment linkages where a permanent fastener is not practical. The zinc-plated finish makes it appropriate for indoor and moderately sheltered outdoor environments.

Key Features

• 0.5-inch pin diameter fits standard through-hole configurations in that size range
• 4.5-inch usable length accommodates multi-layer stack assemblies
• 4130 alloy steel construction provides strength beyond standard mild steel
• Zinc-plated finish adds corrosion resistance for general-purpose environments
• L-handle design enables tool-free, single-hand insertion and removal
• Quick-release mechanism speeds up disassembly in high-cycle maintenance scenarios

Compatibility

Designed as a standard quick-release L-handle pin for use in mechanical assemblies, fabricated fixtures, and equipment linkages requiring a 0.5-inch diameter through-hole fastener with a 4.5-inch usable engagement length.

Installation Notes

Installation requires no special tools — align the pin with the through-hole and seat fully until the release mechanism engages. Verify hole diameter and stack thickness match the pin diameter and usable length before installation. Inspect the release mechanism for proper function before placing the assembly into service. Follow applicable machine guarding and fastener standards for the specific application.
