## Questions & Answers

**Q: How far to set the sj-6 apart from each other? 53'x30' size of the house.**
A: These temporary support jacks have weight limits listed in the product description in my application I was supporting a 8’ x 20’ three thousand pound roof and used 3 4x4 posts with 2 x 8’s screwed in a tee and set at a 35 degree angle for lateral support until the new permanent posts were in place, you can do a section one post at a time

**Q: How deep does the post (4x4) sit within the box frame?**
A: The inside depth is 5 inches, Don't forget to use the holes provided to screw the 4X4 in place for safety.

**Q: How is the U-shaped handle rotated? The video shows the U-shaped handle rotating as if by magic. I want to use it to lift a sagging porch.**
A: You can rotate it by hand.  If you are looking to lift a heavy load I would check out the Ellis Light Duty Steel Lifting Shores.  These use a 3/4" solid steel rod to turn the patented nut assembly with integrated thrust bearings and can lift up to 10x more than the standard screw jacks.

**Q: How many jacks are included? the description says "1", but the second photo shows an open box with two jacks next to it...**
A: I ordered 2 of the 6 x 6 jacks and 2 of the 6 x 6 beam brackets that go at the top of the post.  I received a jack and a bracket in each of the two boxes sent.  I believe two jacks would fit in one of their standard boxes if you only ordered two jacks.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Pay for Quality and Safety
*by S***  on July 23, 2024*

These are heavy duty jacks with welds through and screws that lift without hang ups. Even the paint is hardened. I’m using the jacks for temporary supports to make repairs to my house and safety was the most important factor during repairs. I purchased 2 sets and will purchase an additional pair as peace of mind is apparent!

### ⭐⭐⭐⭐⭐ Works great
*by Y***E on June 22, 2025*

Exactly what was needed

### ⭐⭐⭐⭐⭐ Sturdy and Secure
*by D***H on September 21, 2020*

I bought an old house that is on a hill. It is supported with posts / beams with the posts resting on pier blocks. This summer I went through and replaced many of the pier blocks with diamond piers to stabilize the house and prevent it from sliding down the hill. I bought four of these screw jacks and can't be happier with how much easier they are to use than a car jack for this project. The stability of these screw jacks is amazing as one side slides into the screw jack and the other side can be nailed or screwed in place. I am really glad I purchased them for this project.
