Only a hammer is needed to assemble the Column Form Clamps. They can be used for square or rectangular columns. Hook the bars together and drive the wedge down to tighten each corner. Quickly dismantle by tapping the wedges from the holes in the Column Clamps. Each bar can be nested together for storage.
The bars have been designed to fit columns at 1" increments using 5/8" or 3/4" plywood and 2x4" or 2x6" studs.
Each bar size has a 15" range of adjustment. For example - the SB-48 can be used on net concrete column sizes ranging from 33" to 48".
