Gibraltar LBL-136 Quick-release Pin 3/8 in 2 in 4130 Steel

Product Description

The GIBRALTAR LBL-136 is a quick-release pin with an L-handle, designed for fast, tool-free insertion and removal in mechanical assemblies, jigs, fixtures, and industrial equipment. The pin measures 3/8 inches in diameter with a 2-inch usable length and is machined from 4130 alloy steel with a zinc-plated finish for corrosion resistance. Weighing 0.138 pounds, it is a compact, durable fastening component suited for applications where frequent disassembly is required. Machinists, maintenance technicians, and fabricators typically install this type of pin in production environments and field service settings.

This quick-release pin is appropriate for use in mechanical fixtures, tooling setups, machine guarding, and structural assemblies where repeatable positioning and rapid changeover are priorities. The L-handle configuration allows for positive grip during pin engagement and release without requiring additional tools. It is well suited for both light industrial and heavy-duty fabrication environments where alloy steel strength and a corrosion-resistant finish are necessary.

Key Features

• L-handle design allows tool-free insertion and removal for fast component changeover
• 3/8-inch pin diameter and 2-inch usable length for standard fixture and tooling applications
• 4130 alloy steel construction provides high tensile strength and durability
• Zinc-plated finish offers corrosion resistance in shop and field environments
• Inch measurement system compatible with standard U.S. tooling and fastener specifications

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies, fixtures, and tooling systems requiring a 3/8-inch quick-release pin with a 2-inch usable length in the inch measurement system.

Installation Notes

Quick-release pins of this type are installed by maintenance technicians and fabricators without specialized tools. Always ensure the receiving hole is properly sized and aligned before inserting the pin to avoid binding or premature wear. Verify the pin is fully seated and the release mechanism is engaged before applying load. Inspect the pin and retaining hardware regularly for wear, deformation, or corrosion in high-cycle applications.
