Adjustable Floor Jack Post - Size Range 4'5"-7'9" (15Ga)

I use these to support two additional beams I installed perpendicular to my floor joist in my crawl space. They are not holding up the weight of the house as if they were on a main beam, the 4x6 poplar wood beams that I installed are mainly to stop some deflection in my floor. For that these supports are working fantastic! I especially liked the sturdy construction of them and the quality of construction.That said I highly recommend this product.

Not sure if it happened in shipping, production or if the product was used but the narrow post end that the jack screw sets on was bent and it would not let the screw set in it properly. Had to used a set of plyers to reshape it properly.

We removed the old hot tub from our deck and covered the opening with 4x4 beams and 2x8 boards. We used the jacks to give firmness and take most of the load. If the deck gets wobbly in the future, easy to re-adjust. (Even posts in cement might settle.)Note these do not provide any lateral stability. Suggest the jacks be used, as in our case, where if they fail, no structure is at risk of collapse. (Even if jacked entirely in the air, 2x4 inside each corner prevent it from sliding.)

I bought three of the 2-pack smallest size to add supports under my wood deck. Other than crawling around under the deck in the dirt, they were easy to assemble, which I did by myself. Given they’re steel and how they’re designed, my deck really feels more secure now to support a pergola and roof.One pack had a piece that was stuck (not even WD-40 loosened it) and had to be returned. I received the replacement pair two days later, even though I hadn’t yet returned the defective one which I since did.Good product and well worth the peace of mind for a stronger and longer-lasting deck.

It does the job so I ordered a 2nd.Tube looks strong but not 18K lbs strong at the base. The base plate is thin and the welds to the tube need improving but it will be sitting on a 2"x12" so it's ok.

Works well

This pole is very sturdy, but the first package a plate had slipped through a hole in the box, so I had to get a replacement.The fact that the end caps don't attach in any way is very annoying, as they repeatedly fall off while you try to set it up.

I purchased these jacks to hold up my hard top queen bed slide out on my camper ! To say my camper was sturdy is an understatement this Jack held up 500lbs with not trouble ! Well worth the money!
