Rims have preformed attachment tabs at 12", 16", 19.2" or 24" o.c. spacing to eliminate layout time. The tabs are also prepunched to ensure fast, accurate and proper fastener placement. Embossed stiffening ribs on each side of the preformed tabs provide additional reinforcement, resulting in a significant reduction of web stiffeners (squash blocks) and support clips in a majority of applications. Once rims are installed, simply tilt up the floor joist, abut to the tab and screw attach.
