Spring Nuts
A spring nut is a channel nut with a retained spring that holds it in place inside a strut channel before the bolt is tightened. The spring lets the nut slide to any position along the channel and stay put.
Used to attach pipes, conduit, cable tray and brackets to strut channels in electrical and mechanical installations. Bought by electrical and HVAC contractors.
