The rack is made from 64 inch of 4" channel and 38 feet of 3" channel and two fixed and two movable 600# casters welded together.
The original count of 150 was a W.A.G. from one of my students. The correct count is 209 clamps on the rack. The 25 clamps that are too long are stored in the closet or in the table that I designed and had in FWW issue 174.
