Gibraltar LBR-143 Quick-release Pin 1/2 in 4130 Steel

Product Description

The GIBRALTAR LBR-143 is a button-handle quick-release pin machined from 4130 alloy steel with a zinc-plated finish for corrosion resistance. The pin measures 0.5 inches in diameter with a 1.5-inch usable length, making it suited for light-to-medium duty fastening and alignment applications where fast removal and reinstallation are required. The zinc plating provides a protective barrier against oxidation in typical shop and field environments. This pin is installed by maintenance technicians, fabricators, and equipment service professionals working on mechanical assemblies, jigs, fixtures, and structural connections.

The LBR-143 is intended for use in mechanical assemblies that require frequent disassembly or adjustment without tools. Typical applications include equipment panels, hinged guards, material handling fixtures, and structural alignment tasks in industrial and fabrication settings. The button-handle design allows single-hand operation, reducing service time on repetitive removal tasks. This pin is specified in inch measurements and is suited for both production and field maintenance environments.

Key Features

• 4130 alloy steel construction for strength and durability in mechanical fastening applications
• Zinc-plated finish provides corrosion protection in shop and field conditions
• 0.5-inch pin diameter with 1.5-inch usable length for precise fitment in standard hole patterns
• Button-handle design enables tool-free, single-hand operation
• Inch-system dimensioning for compatibility with standard U.S. mechanical assemblies

Compatibility

Designed as a standard quick-release pin for mechanical assemblies, fixtures, jigs, and equipment panels requiring a 0.5-inch diameter pin with a 1.5-inch usable length.

Installation Notes

Quick-release pins are installed and removed by hand without special tools. Ensure the receiving hole diameter matches the pin diameter before installation to prevent excessive play or binding. Verify that the pin is fully seated and the button release is functional before placing the assembly into service. Follow applicable equipment manufacturer guidelines when using quick-release pins in load-bearing or safety-critical applications.
