4Dimension channel nuts
The 4Dimension strut system is designed for building and installing support systems for electrical, mechanical, plumbing, HVAC, and data centers in both new and retrofit industrial and commercial applications.
The system is compatible with 90 percent of current B-Line series fittings and accessories, and includes unique 4Dimension channel nuts, spring nuts, strut nuts, and accessories. Each accessory features a unique design that works seamlessly with the multi-sided channel of the 4Dimension strut system.
4Dimension dove-tail twirl nut
The 4Dimension dove-tail twirl nut significantly reduces installation time by easily inserting it any length of the dove-tail side of 4Dimension strut.
4Dimension dove-tail slide-in nut
The 4Dimension dove-tail slide-in nut allows for increased job-site flexibility. The nut can be used on all four sides of the 4D22 and the dove-tail side of the 4D21 4Dimension strut system. This allows the full length of the channel to be used, allowing installers to maximize space in small spaces.
4Dimension dove-tail combo nut washer
The 4Dimension dove-tail combo nut washer is designed to install into the dove-tail side of the 4Dimension channel. This eliminates the need for a flat washer and cuts down on the number of parts needed for assembly. Additionally, the washer helps to reduce overall install time which saves both time and money on project costs.
The unique design of the 4Dimension strut channel nuts can be used on multiple sides of the 4Dimension strut channel, allowing for numerous designs and applications. The 4Dimension slide-In nuts can also be used with traditional strut.
The 4Dimension channel fittings and accessories work seamlessly with the 4Dimension strut system. For additional specifications and details, view or download the 4Dimension catalog.
