Gibraltar LBR-145 Quick-release Pin 1/2 in 4130 Steel

Product Description

The GIBRALTAR LBR-145 is a quick-release pin with a button handle, designed for fast, tool-free removal in mechanical assembly and fixture applications. Built from 4130 alloy steel with a zinc-plated finish, this pin offers corrosion resistance and reliable shear strength in demanding environments. It features a 0.5 inch pin diameter and a 2 inch usable length, making it well suited for securing jigs, guards, linkages, and adjustable components where frequent repositioning is required. Machinists, fabricators, and maintenance technicians are the primary installers of this type of hardware.

The LBR-145 is used in industrial machinery, fabrication fixtures, tooling setups, and general mechanical assemblies where quick disassembly without tools is a priority. The button-style handle allows single-handed operation, which is useful in tight access areas or when one hand is occupied steadying a workpiece. This pin follows inch measurement standards and ships in a quantity of one per package.

Key Features

• Button handle enables tool-free, single-handed pin removal and insertion
• 4130 alloy steel construction provides high tensile and shear strength
• Zinc-plated finish offers corrosion resistance in light-duty and shop environments
• 0.5 inch pin diameter suits common fixture and jig hole patterns
• 2 inch usable length accommodates standard wall thicknesses and assembly depths

Compatibility

Designed as a standard inch-series quick-release pin for use in mechanical fixtures, jigs, guards, and adjustable assemblies requiring a 0.5 inch diameter retaining pin with a 2 inch usable length.

Installation Notes

Installation requires no special tools. Verify that the receiving hole diameter matches the 0.5 inch pin diameter with appropriate clearance before installation. Ensure the assembly is in a stable, de-energized state before inserting or removing the pin from any load-bearing or safety-critical application. Inspect the button mechanism and locking detent for wear or deformation during routine maintenance intervals.
