These are sturdy and easy to install. I used them to prop up a sagging floor in a bedroom. However, you many have to prop up the bottoms with blocks as the travel distance is limited.

Awkward design as top plate has to rotate to elevate. This becomes a problem as weight picks up. I used the set I bought but had to jack up floor to get these supports properly adjusted, then lowered floor onto these supports.

I needed something to help support the floor joists. These feel sturdy, not flimsy at all. I didn't know what to expect with these jack stands because I've never purchased any like these before. I was so grateful for the video review created by another buyer which sold me on them. The 3-in top plate holds two, butted 2x4's without any overhang. I would purchase these again without hesitation. But I could be wrong, I did marry my ex.

Review for Duvecfoi 4 Pcs Adjustable House Floor Jack Posts for Support, 13"-16" Height Screw Jack, Each Supports 3000-6000 Lbs, DIY House Jacks Ideal for Basement, Stairs and Crawl Space Stabilization, Gold. A few points: 1) Make sure that you measure your gap plus whatever the jack will sit on. These jack posts only have a 3" range of adjustability. You must buy the right height jack. 2) Make sure that you know the weight that the jack stand can carry. This post is rated up to 6,000 pounds. The more jacks that you use, the weight is spread out between the jacks. 3) The jack's base should sit on a level surface, such as a cement block or wood beam. The weight that the jack is able to carry depends partially on the support underneath the jack. (Tip: Place a concrete block on the ground. Level it. Place pressure treated wood on top of the concrete block, as this prevents the concrete block from cracking over time. Place jack on top of the wood. Then adjust the jack height. Make sure that you have a carpenter's level to check that both top and bottom are level.) 4) The jack's flat top will push up against a solid, flat surface (like a floor joist). The vertical post is what carries the weight, so place the post directly under the center of the weight. The flat top is not what carries most of the weight. 5) If this jack is used to support floor joists, the top flat plate can be screwed to the floor joist above. 6) If you are using this for a camper or other similar purpose, then they make scissor jacks, drop leg jacks, RV jacks, and other types of jacks that might work better.
