Gibraltar LBL-127 Quick-release Pin 5/16 in 3 in 4130 Steel

Product Description

The GIBRALTAR LBL-127 is a quick-release pin with an L-handle, designed for fast, tool-free insertion and removal in mechanical assemblies, jigs, fixtures, and equipment panels. The pin measures 5/16 inch in diameter with 3 inches of usable length. It is manufactured from 4130 alloy steel with a zinc-plated finish for corrosion resistance. The L-handle provides a positive grip for operators working in tight or repetitive-access applications. This pin is typically installed by millwrights, maintenance technicians, and fabricators in industrial and light manufacturing environments.

The LBL-127 suits applications where frequent component removal or adjustment is required without tools. Common uses include machine guarding, fixture alignment, safety interlocks, and equipment positioning. The quick-release mechanism allows for rapid disengagement under light to moderate loads. It is appropriate for both shop floor and field service use where a reliable, repeatable pin solution is needed.

Key Features

• Quick-release mechanism allows tool-free pin removal
• L-handle design provides positive grip and fast actuation
• 5/16 inch pin diameter suits standard clevis and fixture bores
• 3 inches of usable length accommodates typical panel and assembly thicknesses
• 4130 alloy steel construction for strength and durability
• Zinc-plated finish provides corrosion resistance in general-duty environments

Compatibility

Designed as an OEM-style and aftermarket replacement quick-release pin for mechanical fixtures, jigs, machine guards, and equipment assemblies requiring a 5/16 inch diameter pin with 3 inches of usable length.

Installation Notes

Installation requires no special tools — insert the pin through aligned bores and engage the quick-release mechanism by hand. Verify that the receiving bore diameter matches the 5/16 inch pin diameter before installation. Inspect the pin and release mechanism for wear or deformation before each use in load-bearing or safety-critical applications. Removal and reinstallation should be performed only when the assembly is stationary and not under load.
