The Mega-Track Hanger makes it easy to hang 140 or 300 series track onto pipe grids, or from individual pipes, and hangs from the upper pipe of the grid and has an offset length from the track to the pipe the diameter of the bottom grid pipe plus 3/16 of an inch. The Mega-Track hanger Long has two different track hanging slots so that it will work with either 1-1/2" or 1-1/4" schedule 40 pipe grids. It uses a Mega-Gridlock half to fasten over the pipe and secure from below with four 5/16" socket head screws. The Mega-Gridlock half has slots along the edge that act like a wrench to hold the four Nylock nuts from turning during installation. Only a slight downward pressure with your fingers is required to hold a nut in place for installation. The track hanger slides over the track prior to placing the track in position. Support track approximately every 4 feet.
