Flanges are 3-5/8" overall diameter, 1/8" thick, and have (6) ¼" diameter mounting holes equally spaced on a 3" diameter hole pattern. Jacks are made of steel with a polished chrome finish and have an 8½" long handle that folds down when not in use. They stand on a 3-7/8" diameter swivel base that has a slip-resistant rubber pad on the bottom. Screw diameter is 1¼". Lift rate is ¼" per crank revolution.
