Abb B9111/2 1/2 Inch Spring Nut Strut Fitting

Product Description

The ABB B9111/2 is a 1/2 inch spring nut designed for use with channel strut framing systems. Spring nuts clip directly into the channel slot and allow hardware to be positioned and repositioned along the strut without requiring full disassembly. The spring tension holds the nut in place during layout and tightens securely when the fastener is driven. This type of fitting is a standard component in strut-based support systems used throughout commercial and industrial electrical, mechanical, and plumbing installations. Electricians and mechanical contractors install spring nuts when building pipe hangers, cable tray supports, equipment mounts, and similar framing assemblies.

The B9111/2 is suited for use in strut channel support applications where a 1/2 inch fastener is required. These fittings are commonly installed in commercial buildings, industrial facilities, and utility rooms as part of prefabricated support structures. The package dimensions indicate this is a bulk or multipack configuration, making it practical for larger projects requiring multiple connection points throughout a strut assembly.

Key Features

• 1/2 inch thread size for compatibility with standard strut hardware
• Spring-loaded design holds nut in channel slot during positioning
• Allows repositioning along strut without full hardware removal
• Suitable for electrical, mechanical, and plumbing support assemblies
• Bulk packaging supports larger installation projects

Compatibility

Designed as an OEM-style replacement fitting for standard 1-5/8 inch channel strut framing systems accepting 1/2 inch spring nut hardware.

Installation Notes

Spring nuts are installed by electricians and mechanical contractors as part of strut support assemblies governed by NEC and applicable building codes. De-energize any nearby electrical systems and relieve pressure from any supported piping before modifying an existing strut assembly. Insert the spring nut into the channel slot at an angle, then rotate to lock it in position before threading the fastener. Avoid overtightening fasteners, which can distort the spring clip and reduce holding strength.
