Gibraltar LBT-143 Quick-release T-handle Pin 4130 Steel

Product Description

The GIBRALTAR LBT-143 is a T-handle quick-release pin designed for fast, tool-free removal in mechanical assemblies, jigs, fixtures, and equipment access panels. The pin features a 0.5 inch diameter and a 1.5 inch usable length, machined from 4130 alloy steel with a zinc-plated finish for corrosion resistance. The T-handle design allows for one-handed operation, making it well suited for applications where frequent disassembly and reassembly are required. This pin is a standard inch-system component intended for installation by maintenance technicians, millwrights, and mechanical assemblers working with structural or industrial equipment.

The LBT-143 is used in residential and commercial mechanical applications where a reusable, non-threaded fastener is needed for panel retention, safety guards, linkages, and similar quick-access assemblies. Its compact profile and T-handle grip make it practical in confined or repetitive-access locations. The 4130 steel construction provides adequate tensile strength for light to moderate shear loads typical of fixture and equipment panel applications.

Key Features

• T-handle design enables fast, one-handed, tool-free pin removal
• 0.5 inch pin diameter suits standard quick-release pin hole patterns
• 1.5 inch usable length accommodates typical panel and fixture material stacks
• 4130 alloy steel construction for reliable tensile and shear strength
• Zinc-plated finish provides basic corrosion protection in indoor and light-duty environments

Compatibility

Designed as a standard inch-system quick-release T-handle pin for use in mechanical assemblies, jigs, fixtures, equipment guards, and access panels requiring a 0.5 inch diameter pin hole and 1.5 inch usable engagement depth.

Installation Notes

Installation requires no special tools — insert the pin through aligned holes and the internal detent ball retains it under load. Before servicing any assembly that relies on this pin for structural retention, follow applicable lockout/tagout procedures and de-energize or de-load the equipment. Verify the receiving hole diameter and stack thickness match the pin specifications before installation. Inspect the detent mechanism periodically for wear in high-cycle applications.
