Heavy Duty Support For Any Area

“I had to jack in a little space, about 10" between the house sill and the floor joists, and it worked out great; the space was so tight that a hydraulic jack couldn't go in there, but these fit in as support after you jacked it in place.” - Daniel G.

Why Buy Our House Floor Jack?

DURABLE: It's made of high-quality carbon steel and this has a double carriage lock for added strength and safety. Also, features a corrosion-resistant coating to the self-centering plates (minimum thickness: 0.82") that are designed to reduce movement and prevent dishing.

STABLE: It's easy to install and assemble. All of its moving elements are tightly fitted, to avoid lateral displacement and the top and bottom plates are highly embossed to reduce movement and prevent dishing.
