Gibraltar LBR-133 Quick-release Button Handle Pin 3/8 in

Product Description

The GIBRALTAR LBR-133 is a quick-release pin with a button handle, designed for fast, tool-free insertion and removal in mechanical assemblies, jigs, fixtures, and industrial equipment. The pin body is manufactured from 4130 alloy steel with a zinc-plated finish for corrosion resistance. It features a 3/8-inch pin diameter and a usable length of 1.25 inches. The button-actuated release mechanism allows single-hand operation, making it well suited for applications that require frequent pin removal or adjustment without tools. Machinists, maintenance technicians, and fabricators install this type of pin across a wide range of industrial and trade settings.

This pin is commonly used in fabrication shops, manufacturing jigs, agricultural equipment, material handling fixtures, and general mechanical assemblies where a clevis or hitch pin would create unnecessary downtime. The 3/8-inch diameter and 1.25-inch usable length make it appropriate for light- to medium-duty connections in Inch-system components. It ships individually and is sold as a single-piece quantity.

Installation Notes

Installation requires no tools — insert the pin through aligned holes and confirm the button-locking detent engages fully before applying load. Before servicing any assembly that uses this pin, relieve tension or load on the connected components to prevent unintended movement during removal. Inspect the pin body and locking mechanism for wear or deformation before each installation in load-bearing applications. Follow applicable ASME or equipment manufacturer guidelines for pin-retained connections.
