Gibraltar TPOP-4700- G Weld-in Pull Pin 3/8 in Zinc-plated

Product Description

The GIBRALTAR TPOP-4700- G is a weld-in pull pin with a T-handle, designed for quick-release locking and positioning applications in industrial and mechanical assemblies. The pin features a 3/8-inch diameter, a 0.6-inch usable length, and a 3.75-inch overall length. The pin body is machined from 1018 steel with a zinc-plated finish for corrosion resistance. The T-handle is molded plastic, allowing fast manual actuation without tools. Machinists, maintenance technicians, and fabricators install this type of pin in jigs, fixtures, hinges, and adjustable stops where repeated manual engagement and release is required.

This weld-in pull pin is suited for light to medium-duty industrial applications where the pin base is permanently attached to a weldment or fabricated frame. Typical scenarios include positioning fixtures, adjustable guards, locking arms, and hinged panels in manufacturing and shop environments. The weld-in design provides a permanent, stable anchor point, while the pull-style T-handle allows fast, tool-free pin removal and re-engagement during setup or adjustment cycles.

Key Features

• Weld-in base for permanent, stable installation in fabricated assemblies
• 3/8-inch pin diameter with 0.6-inch usable length for precise positioning engagement
• 3.75-inch overall length suits standard fixture and frame depths
• 1018 steel pin body offers reliable strength for repeated cycling
• Zinc-plated finish provides corrosion resistance in shop and light industrial environments
• Plastic T-handle enables fast, tool-free manual actuation

Compatibility

Designed as an OEM-style weld-in pull pin for use in fabricated fixtures, adjustable assemblies, hinged guards, and positioning jigs where a 3/8-inch pin diameter and weld-in retention are required.

Installation Notes

Installation is performed by welding the pin base into the host weldment or frame before final assembly. Ensure the weld joint is fully cooled and inspected before placing the assembly into service. Verify pin alignment with the mating receiver or hole prior to final welding to prevent binding during pull-release operation. Wear appropriate PPE during welding operations and follow applicable shop safety procedures.
