Clamping Nuts

Sasco Clamping Nuts are fundamental to the Sasco Suspension System. They ensure positive locking between the nut's serrated grooves and the Strut Channel. When they are inserted anywhere along the continuous slot of the channel they allow attachment of fittings without drilling or welding. If changes are required, fittings are easily adjusted, removed or reused.
