Gibraltar LBH-128 Quick-release Pin 5/16 in Ring Handle

Product Description

The GIBRALTAR LBH-128 is a ring-handle quick-release pin designed for fast, tool-free fastening and removal in mechanical assemblies, fixtures, and industrial equipment. The pin measures 5/16 inch in diameter with a 3-1/2 inch usable length and a 4-3/4 inch overall length. Constructed from 4130 alloy steel with a zinc-plated finish, it delivers corrosion resistance alongside the strength required for repeated insertion and release cycles. The ring handle allows one-handed operation, making it a practical choice for applications where frequent disassembly or adjustment is required.

This quick-release pin is suited for use in manufacturing jigs, agricultural equipment, material handling rigs, and general mechanical assemblies where temporary or removable fastening is needed. It is commonly installed by maintenance technicians, machine builders, and field service personnel working on equipment that requires regular component removal or repositioning. The inch-system dimensions make it a direct fit for standard American fastener applications.

Key Features

• Ring handle enables tool-free, one-handed operation for fast release and insertion
• 4130 alloy steel construction provides high tensile strength for demanding applications
• Zinc-plated finish offers corrosion resistance in light-duty outdoor or industrial environments
• 5/16 inch pin diameter with 3-1/2 inch usable length suits a wide range of standard fastener holes
• 4-3/4 inch overall length accommodates typical assembly stack-ups with clearance for the ring handle

Compatibility

Designed as a standard inch-system quick-release pin for mechanical assemblies, fixtures, and equipment requiring a 5/16 inch diameter removable fastener with a 3-1/2 inch usable length.

Installation Notes

Install and remove by hand using the ring handle — no tools are required under normal operating conditions. Ensure the receiving hole diameter is clean and free of burrs before insertion to prevent premature wear on the pin or detent mechanism. Verify the pin is fully seated and the detent ball or locking feature is engaged before placing the assembly under load. Inspect the pin and hole periodically for wear, deformation, or corrosion that could compromise retention.
