HellermannTyton panel rivets are one piece drive rivets that provide a fast, economic means of affixing wiring duct. The rivet is inserted into a 3/16” pre-punched hole and the pin is driven into the base, thereby expanding the rivet legs and locking the duct and sub-panel in place. The panel thickness (including the duct thickness) should be a maximum of 3/16”. A panel rivet tool is also available for quick and easy installation of the drive rivets.
