Wall Jacks provide an easy way to lift prefabricated walls into a vertical position, up to 70 ft. long. The available high-quality wall jacks come as a two pack and are offered in either 16 ft. or 20 ft. options. Each 16 ft. jack can lift walls up to 1,000 lbs. at a maximum wall height of 10 ft. 6 in. Each 20 ft. jack can lift a wall up to 500 pounds with a maximum wall height of 13 ft. 6in. These wall jacks have a safety pin that is used to hold the upper and lower tubes in a lifting position and are easy to carry from each job site. Additionally, they feature square tubing, which is stronger and easier to use than round tube models.
