FUNCTIONS AND FEATURES

Combo Nut Washer is a pre-assembled nut and washer, which helps reduce the number of parts that require handling. The combination design allows for easy adjustment when installed in strut channel, and provides quick attachment for threaded rod, allowing a simple installation using just one hand, which helps reduce installation time and cost. Furthermore, the serrated flange negates the need for a flat washer.
To install, position Combo Nut Washer into strut channel and rotate clockwise as nut seats in the strut channel. Then slide Combo Nut Washer into the desired location in the strut channel and insert threaded rod into nut, the Combo Nut Washer locks at 90 degree angle. Then thread the rod up through the nut and lock into place with a hex nut, now the threaded rod is ready for products to be installed.
Spring Nuts are one of the main components of the suspension system, they are inserted anywhere along the continuous slot of the channel, allowing the attachment of fittings without drilling or welding. If changes are required, fittings are easily adjusted, removed, or reused.
Designed with specially formed teeth in the parallel channel recesses to grip the returned edge of the channel, and the shearing action of the teeth assures positive locking of the channel to the fittings.
Spring Nuts with regular spring have shrink wrap sleeves on them eliminating tangling during shipping and installation.
