Gibraltar LBL-149 Quick-release Pin L-handle 4130 Steel

Product Description

The GIBRALTAR LBL-149 is a quick-release pin with an L-handle designed for fast, tool-free installation and removal in industrial, mechanical, and structural applications. It features a 0.5 inch pin diameter and a 4 inch usable length, making it well suited for medium-load positioning, locking, and alignment tasks. The pin is manufactured from 4130 alloy steel with a zinc-plated finish that provides corrosion resistance in moderate environments. Machinists, maintenance technicians, and fabricators install this type of pin where frequent manual adjustment or component removal is required without the use of hand tools.

The LBL-149 is used in a wide range of industrial and fabrication environments, including jigs, fixtures, carts, frames, and equipment guarding where a repeatable, secure pin connection is needed. The L-handle configuration allows for a positive grip during insertion and extraction, even in confined spaces. This pin is appropriate for both light manufacturing settings and general-purpose maintenance applications where standardized inch-measurement hardware is specified.

Key Features

• L-handle design allows tool-free, one-hand pin removal in frequent-adjustment applications
• 0.5 inch pin diameter and 4 inch usable length for medium-load positioning tasks
• 4130 alloy steel construction for strength and durability under mechanical stress
• Zinc-plated finish provides corrosion resistance in moderate-exposure environments
• Inch measurement system for compatibility with standard U.S. fabricated assemblies

Compatibility

Designed as a standard inch-series quick-release pin for use in jigs, fixtures, carts, frames, and other fabricated assemblies requiring a 0.5 inch pin diameter with 4 inch usable engagement length.

Installation Notes

Installation is typically performed by maintenance technicians or industrial assemblers without specialized tools. Ensure the receiving hole is clean, properly sized, and aligned before inserting the pin to avoid binding or damage to the locking mechanism. Always verify that the quick-release retention feature is fully engaged before applying load. Inspect the pin and locking ball or clip regularly for wear, especially in high-cycle or high-vibration applications.
