        Just used this jack for a post replacement on an addition,tons of power with no creep after 3 days. Handle is a great feature. Jet really outdid themselves with this jack in both design and performance.

        Comments about SJ-20, 20 Ton SJ Series Screw Jack:

        I bought these jacks (2) for my current house project. This is what you call a "lifetime" tool. You may only need them a few times in your life but if you own an old house, you WILL need them. This is also an excellent tool to loan out to friends because it is so heavy duty that it won't come back broken. Let's face it, most people will never need to lift 20 tons but my feeling is that a 20-ton jack will last twice as long as a 10-ton jack when lifting 10 tons.
