The Mega-Track Hanger makes it easy to hang 140 or 300 series track onto pipe grids, or from individual pipes. There are two versions of the Mega-Track Hanger. The Mega-Track Hanger Short hangs from the lower pipe of the grid and secures the track just 3/16 of an inch below the grid pipe. The Mega-Track Hanger Long 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. Both of the Mega-Track Hangers use 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.
