Show Solutions Extension support frame with screw jacks with 12" box truss bolt pattern for SS-block

An extension support frame fitted with screw jacks and drilled to the 12" box truss bolt pattern, built to work with the SS-Block. The jacks let you level the frame on a raked, cambered or plain uneven floor and take up the last inch of height by hand instead of shimming under a leg. Because the bolt pattern is the standard 12-inch pattern, stock box truss and the matching block hardware attach directly. Use it to extend and foot a ground-support position.
