Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
How do I know which height I need?
+
Measure from the floor where the post will stand to the underside of the beam or joist it will support. If that number falls between 54 and 150 inches (1,372–3,810 mm), the post will fit.
Do I need anything between the post and the beam?
+
Make sure the top of the post sits fully and squarely against the beam or joist. Many people add a solid wood block or steel plate to spread the load across a wider area. Confirm the right approach for your structure with a contractor.
Can I use one post, or do I need both?
+
That depends on the job. A short span or a single point load may only need one post. Longer sagging spans and beams supported at two points benefit from using both. When in doubt, a contractor can tell you how many support points your span needs.
Will this fully fix my sagging floor?
+
It gives the floor support and lets you lift it back toward level. A sag can come from rot, undersized joists, or a failing footing. For a permanent fix, have the underlying cause looked at by a professional.
Should I load the post to its full rated capacity?
+
It’s good practice to stay well below any jack’s maximum rating and leave a safety margin. If you’re unsure how much weight your floor or beam carries, consult a contractor or structural engineer.
Can I leave the posts in place long term?
+
These posts are designed for temporary support. If you need permanent support, check your local building codes, since many areas require approved permanent columns, footings, or an inspection.
What surface should the post stand on?
+
Use a solid, level surface such as a concrete floor or footing. Avoid dirt, soft ground, or cracked or uneven slabs, since they can shift or sink under load.
Is the 11,200 lb rating for one post or both?
+
It’s per post. Each post is rated to hold up to 11,200 lbs (5,080 kg).
