The Wall Jacks by Tie Down offer the safest and most efficient way to lift walls into a vertical position. These wall lifting jacks are constructed of heavy-duty steel tubing and are available in 16 ft., 20 ft., and 23 ft. lengths. After lifting the walls, the Wall Jack combined with the Wall Brace secures the wall into a vertical position. This product safely lifts sheathed walls up to 70 ft. tall. The 10 ft. adjustable brace uses a heavy-duty, 1 in. zinc-plated steel square tube. The head has a 12 in. long ¾ in. diameter fast turn screw and the foot offers a 360° swiveling bracket with no wobble. Tie Down maintains high standards and quality controls using quality raw materials and component parts made in the USA.
