Bench LegsAn ingenious patented slide and track system makes it possible to erect and secure the bench legs with a single downward motion of the brace strut. Step RailThe step rail is easily detached from its stored position on the bench top and snapped onto the legs for step up convenience. Step rail may also be used for a straight edge. Folded BenchConversely, with an upward motion of the brace strut the legs are unlatched, folded, and stored entirely within the 3" bench top. Twist-lock SystemLeg lengths are rapidly adjusted with a unique patented twist-lock pin system which allows legs to be unlocked and adjusted with a simple twist of the wrist. Adjustments are from 18" to 30" in 2" intervals. Rubber End BumpersRubber end bumpers protect woodwork, car doors, and walls.
