Show Solutions Steel 48" x 48", 9mm thick top plate on a 1" raised frame with 1 welded 1-1/2" schedule 40 flange

A 48" x 48" steel base plate with a 9 mm thick top on a 1-inch raised frame and one welded 1-1/2" schedule 40 flange. The flange is the point of difference: it accepts a schedule 40 pipe upright directly, so you can stand a pipe-and-base structure without a separate adapter. Steel rather than aluminum means the plate itself contributes real ballast weight, and the four-foot square footprint gives a wide base for taller uprights. The raised frame allows cable to route under the plate.
