Gibraltar LBR-148 Quick-release Pin 1/2 in 3.5 in 4130 Steel

Product Description

The GIBRALTAR LBR-148 is a button-handle quick-release pin designed for fast, tool-free removal in mechanical assemblies, fixtures, and industrial equipment. Machined from grade 4130 steel with a zinc-plated finish for corrosion resistance, this pin features a 0.5-inch diameter and a 3.5-inch usable length. It is installed and removed with a simple push-button action, making it well suited for applications that require frequent disassembly or adjustment. Machinists, maintenance technicians, and fabricators typically specify this type of pin where a standard clevis pin or cotter pin would create unnecessary downtime during servicing.

The LBR-148 is appropriate for use in jigs, fixtures, agricultural equipment, material handling systems, and general industrial machinery. Its inch-system dimensions make it a direct fit for applications engineered to standard imperial tolerances. The button-handle design allows single-handed operation, which is an advantage in tight or awkward installation positions. It is sold as a single unit and is available for individual replacement or small-quantity procurement.

Key Features

• Button-handle design allows tool-free, single-handed pin removal
• Grade 4130 steel construction for strength and durability in mechanical load applications
• Zinc-plated finish provides corrosion resistance in general-duty environments
• 0.5-inch pin diameter with 3.5 inches of usable length
• Inch-system dimensions suit standard imperial-tolerance assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit component for imperial-dimensioned quick-release pin applications requiring a 0.5-inch diameter button-handle pin with 3.5 inches of usable length.

Installation Notes

Installation requires no special tools — insert the pin through aligned bores and allow the spring-loaded button to seat before applying load. Before servicing any assembly, de-energize or depressurize the equipment per the manufacturer's service procedure. Verify bore diameter and required usable length against the assembly drawing before installation. Inspect the pin and button mechanism for wear or deformation before each reuse in safety-critical applications.
