🏋️ 2 Pack of Akron Adjustable Floor Jacks (Model C-4), Telescoping Jacks for Temporary Support, Size Range 1'-1' 3 Review

I've bought other sockets that are completely soldered together, I don't think you can get them at this price. I didn't feel safe temporarily supporting my house while replacing a few poles underneath. I ended up welding them together so I didn't need 4 hands to install it and pray it wouldn't bang and fall apart. After I welded everything they work fine.

Worked well enough when in place but the top plates warped badly when I tightened the bushings fairly well with a wrench, they are too thin to hold. So now the load is poorly distributed to the top plates. The bottom plates were fine as the bushings touched the flat part of the plates. The screws were ok. The picture isn't clear, but there is a bulge at the top of the threaded section that fits into a hole in the top plate. It would be difficult to reuse them, so leave them in place.

Great product, I will actually order another set for more buoyancy. I used this to build my house which stands on a pole and pier. Fix a broken mast and a sinking pillar. They come in pieces but I welded the base to the tube and bolt to tube with a quick weld and worked like a champ. DO NOT weld the top plate, otherwise it will be difficult for you to lift the screw. I did it on one, and in the middle of the weld it was oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo…

They are simple and easy to use. You really should use a bottle jack to aim the jet where you want it and then plug it in for support. It will take a lot of strength to keep turning the screw with the wrench if you have to lift a lot. The hose can be trimmed to make it shorter if needed, or you can purchase a longer hose if you prefer. There are 4 of them. I would weld them together with oven mitts or even silicone or JB if you're working in a basement. You don't want to try to pull and keep…

. They work, but it's a bit of a hassle to set them up. Everything must be perfectly aligned because the four parts are not connected. Install the bottom plate first, then the main pipe. Insert the screw part into the main pipe, and then install the top plate at the top of the screw. hold your breath If you hit it, everything will fall apart. The adjustable stroke is adequate for getting everything in place, as long as you start with the jack in the lowest position and have the right blocks to…

Bolt and nut good, pipe OK. The problem is that the top and bottom plates are flimsy and flimsy and will deform and break under pressure. We machined new plates for the bolt side from 1/4" sheet steel. Just drill a 5/8 hole in the plate. They then work without deforming and crushing the stamped steel bladder. We also used molybdenum grease to grease the threads and the To lubricate the top plate threaded hole. We were able to reinforce the house using a large adjustable wrench and pipe for…

High quality materials but poor design. It consists of four separate parts that fit together in no other way than being held together by the pressure of the object you are trying to support. Can only be used when perfectly perpendicular to the ground and the supported object. If you're lucky and it's lined up perfectly, you'll still need at least four hands to hold everything in place when trying to use it. I went ahead and welded everything together to make it work better. As an extra…

(I am a licensed professional engineer). The product must be installed vertically within 1 degree. Why? because the contact of the adjusting screw plate with the metal cylinder is only 2mm. Mounting plates are sheet metal, not sheet metal. They deform instantly with minimal stress (less than 1000 pounds). Once deformed, all of the weight is on the 10mm x 6mm pivot where the plate sits. Therefore, warped or not, the panels have no structural value. The plates are stamped so the "centering"…

These jacks can carry a full load of 18,000 pounds when extended no more than 15 inches in height. They can get 3 inches more, but they won't support the full weight. It may be okay to lift a sagging floor, but you need full lifting capacity when there is a wall above your lifting point. The comments about weak ground planes are correct. For example, at full load, the plate in which the screw is inserted will shatter until it touches the raised surface. This can easily be stopped by putting 2…
