Gibraltar LBR-119 Quick-release Pin 1/4 in 4 in Steel

Product Description

The GIBRALTAR LBR-119 is a button-handle quick-release pin designed for fast, tool-free connection and disconnection of mechanical assemblies. Machined from 4130 alloy steel with a zinc-plated finish, this pin offers solid corrosion resistance and structural integrity under repeated cycling. It has a 0.25-inch pin diameter and a 4-inch usable length, making it suited for medium-duty linkage, clevis, and fixture applications. Machinists, fabricators, maintenance technicians, and assembly line personnel are the typical installers and users of this fastener type.

This quick-release pin is used in industrial machinery, material handling equipment, tooling fixtures, agricultural equipment, and general fabrication where frequent disassembly is required. The button-handle design allows one-handed operation without tools, reducing downtime during equipment adjustment or component swaps. It is appropriate for both light and medium-duty mechanical connections in shop and field environments where a secure yet removable fastener is needed.

Key Features

• Button handle allows fast, one-handed, tool-free release
• 4130 alloy steel construction for durability under load and repeated use
• Zinc-plated finish provides corrosion resistance in general-service environments
• 0.25-inch pin diameter fits standard clevis and linkage bore sizes
• 4-inch usable length accommodates medium-depth through-hole applications

Compatibility

Designed as a standard inch-series quick-release pin for use in clevis connections, tooling fixtures, and mechanical linkages requiring a 0.25-inch diameter pin with a 4-inch usable length.

Installation Notes

Installation requires no special tools — insert the pin through aligned bores and press the button to lock or release the retaining ball detent. Ensure the receiving holes are clean and free of burrs before insertion to avoid damaging the detent mechanism. Verify that the usable length is sufficient for the full material thickness of the assembly before selecting this pin. Do not use as a shear pin in applications exceeding the rated capacity of 4130 steel at this diameter.
