Gibraltar LBR-152 Quick-release Pin 1/2 in 6 in 4130 Steel

Product Description

The GIBRALTAR LBR-152 is a quick-release pin with a button handle, manufactured from 4130 alloy steel with a zinc-plated finish for corrosion resistance. It features a 0.5 inch pin diameter and a 6 inch usable length, making it suitable for applications that require fast, tool-free pin removal under load or during frequent assembly and disassembly cycles. The 4130 steel construction provides a strong strength-to-weight ratio for demanding mechanical and structural connections. Weighing 0.4 pounds, this pin is a direct fit for industrial, agricultural, and mechanical assembly applications where reliable retention and quick release are essential. Licensed tradespeople and maintenance technicians working with fabricated assemblies or equipment frames are the primary installers.

This quick-release pin is used in applications requiring repeated removal and reinstallation of components without tools, such as securing panels, linkages, gates, equipment guards, or structural members in industrial machinery, agricultural equipment, and fabricated steel assemblies. The button-handle design allows single-hand operation, releasing the locking balls when the button is depressed so the pin can be withdrawn cleanly. Its inch-standard sizing fits standard clevis and lug connections designed for a 0.5 inch pin diameter.

Key Features

• Button handle for single-hand, tool-free release
• 0.5 inch pin diameter with 6 inch usable length
• 4130 alloy steel construction for high strength in demanding applications
• Zinc-plated finish for corrosion resistance
• Inch-standard sizing compatible with standard clevis and lug fittings
• Lightweight at 0.4 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or standard hardware fit for clevis, lug, and bracket connections requiring a 0.5 inch quick-release pin in inch-standard mechanical assemblies.

Installation Notes

Installation requires no special tools — depress the button handle to retract the locking balls, insert the pin through aligned holes, and release the button to lock it in place. Ensure hole diameters and material thickness fall within the designed usable length of 6 inches before installation. Inspect the locking ball mechanism for wear or damage before each use in safety-critical applications. Follow applicable ASME or OSHA standards for pinned connection applications on load-bearing or equipment-guarding assemblies.
