Gibraltar LBL-137 Quick-release Pin 3/8 in 4130 Steel

Product Description

The GIBRALTAR LBL-137 is an L-handle quick-release pin used for fast, tool-free fastening and removal of components in mechanical assemblies, fixtures, and fabricated structures. The pin measures 0.375 inches in diameter with a usable length of 2.5 inches, making it suitable for moderate-load retention applications where repeated access is required. Constructed from grade 4130 alloy steel with a zinc-plated finish, it offers solid corrosion resistance for indoor and light-duty industrial environments. The L-handle design allows quick actuation by hand without the need for additional tools. Technicians and fabricators in manufacturing, maintenance, and equipment assembly commonly work with this hardware type.

This quick-release pin is suited for use in jigs, fixtures, machine guards, agricultural equipment, and general mechanical assemblies where components need to be locked in position and released frequently. The inch-system dimensions and standard 3/8-inch diameter make it compatible with a wide range of drilled hole patterns used in fabricated steel and aluminum structures. One pin is included per package.

Key Features

• L-handle design allows tool-free, one-hand actuation for fast assembly and disassembly
• 3/8-inch pin diameter suits standard drilled hole patterns in fabricated assemblies
• 2.5-inch usable length accommodates moderate-thickness component stacks
• Grade 4130 alloy steel construction provides strength for load-bearing retention applications
• Zinc-plated finish provides corrosion resistance in indoor and light-duty industrial environments

Compatibility

Designed as a standard inch-system quick-release pin for use in mechanical assemblies, fixtures, jigs, and equipment with drilled holes sized for a 3/8-inch pin diameter.

Installation Notes

Installation requires a clean, burr-free hole sized to accept a 3/8-inch pin without excessive slop or interference. Verify that the usable length of 2.5 inches clears the full material stack thickness before selecting this pin. No tools are required for insertion or removal during normal operation. Inspect the release mechanism and pin body periodically for wear, deformation, or corrosion, and replace if any damage is found.
