Show Solutions Steel 36" x 36", 9mm Thick Top Plate on a 1" Raised frame with with 1 welded 1-1/2" schedule 40 flange

A 36 by 36 inch steel base plate, the largest of the common square sizes, with a 9mm thick top plate on a 1-inch raised frame and one welded 1-1/2 inch schedule 40 flange. The bigger footprint and greater plate mass give a tall upright far more resistance to tipping, so this is the plate you reach for on ground-support towers and exposed outdoor positions. The 1-inch raised frame lets cable run beneath the plate and gives you something to get a hand under when repositioning it.
