Guardian 2601 Wall Jack 

The Wall Jack is used to raise walls and beams and tighten flooring and decking. Made of heavy duty, malleable cast iron, the wall jack rides up and down on a 2-by-4-foot pole, working like a car jack for dozens of construction uses. To lift walls and beams insert a length of ¾ inch (OD) pipe (not included) to act as a lever. The Wall jack has a capacity of 1,000 pounds with the use of a 2x4 (actual measurement is 1½" by 3½") made of clear, straight-grained fir wood, free of knots and defects. The jack is intended to meet OSHA safety regulations when instructions are carefully followed. The Wind Hook Accessory Kit provides a complete wall lifting system and can be purchased separately and includes base plate and wind hook cable
