Inside the box is 5 inches deep. Once you've screwed the 4X4 into place, make sure to use the holes provided
A corner at the bottom of the page. In order to keep the 4x4 from rotting, make sure the 4X4 is sealed around the top of the screw jack.
replaced a 6x6 post and patio cover without incident. It is my hope that this will be helpful
The structures are made from heavy steel gauge welded together. A galvanized surface is not possible. It is paint that is orange. The painting is not of the highest quality. There is no paint on the threads, and they are greasy. had some installed under a camp for about 9 years, but they rusted as a result of moisture coming in contact with them. A particularly nasty thread was the one where the grease was scraped off the height adjustment. Even though they are rusted, they are still able to be turned to adjust the height. Rusting will most certainly occur at a much faster rate if the parts are left in water for an extended period. They need to be on a solid base so you can turn them with a 2x4 or pipe due to the rust. You may need a longer 2x4 or pipe. It is necessary for the base it sits on not to be perfectly level to plum the post/jack because there is some play in the square base plate. In lieu of pouring a concrete footing / pilar, I discovered that concrete cap blocks work best as a base on the ground. It is not a good idea to put grease on the threads after installation if they will be I found the installation to be very easy.

Using this shoring jack, I am replacing On average), cement pier blocks, and concrete pier It was too unstable to use a 10 ton bottle jack, so I changed the system. With this Ellis shoring jack, an Ellis top bracket, and four 4x4s I have no problem hoisting the car. There is plenty of stability in that region. Unlike the shoring jack, I'm not here for the following reasons There are certain things that it won't accept (1) The following size 4x4 is available As soon as I am done jacking with it, I chisel out the waste wood (2) I have to use a short bar to lift and lower the jack while down on the ground. If you use a bar for a long time, it may damage the lower jack threads as the tool is in contact with the threads as you turn. It has been exposed for a month to direct sunlight, which has caused the paint to oxidize a bit. The base of the jack, a 4x6, was screwed to it for additional stability and to keep it from sinking. A heavy deck is easily lifted and supported by this deck lift.
As a remodeler, I have been using these products for decades, but I only discovered them about a year or two My life would not be the same without them. These tools are among the most useful ones I've ever acquired. The tool van keeps four of them in it, and we use them constantly for light/medium shoring and It is not necessary to have 4x4s just get a couple of 2x4s of the length you need, screw them together, and you are done. It is a 2 Iron bars 3' in length are good for turning the bottom (the ones Jet sells to go with their screw jacks are good). - No more trying to find steel jack posts, that only range in size from a few inches to a couple feet, that are the right size. - A second pair of 2x4s can be cut if there is another height you need. Yes, these are made in China, but some good old American ingenuity came up with the idea. Unlike cheap junk, they are of high quality. These hold, move, and straighten a lot of residential framing in a short amount of time. If you work on removing and modifying bearing walls (adding headers or beams), upgrading flooring systems, rebuilding old porches, etc. , you need them. Since the LVL, this has been the best thing to remodel structurally.
With an almost effortless turn of the screw, the upper and lower decks were raised to their original positions.
My wife and I recently bought an old farmhouse in a beautiful hillside area. The posts and beams rest on pier blocks with pier blocks supporting the rest of the structure. To stabilize the house and prevent it from sliding down the hill, this summer I replaced many of the pier blocks with diamond-shaped piers. The screw jacks work amazingly well one side slides into the screw jack, and the other side can be fixed in place by nailing or screwing. I bought four of them for my project and they are so much easier to use than a car jack. They are excellent for this project, and I'm so glad I got them.
Do not buy the knock off at a cheap price. There are a lot of amazing Jacks out there. In my 1887 home in Saint Augustine, I am using them to support two 6 X 6 posts that will be the new load point securing the two stories. They are very well made and.
I am blown away by the quality of construction of these stands. There is no substitute for quality, and these stands are quite worth the money!.
My front porch posts needed replacing, and I used this jack to accomplish the task. It was very easy to use and very strong. However, I recommend greaseing the threads before mounting, and cutting a short 2*4 to use as Very well made, fits perfectly on a 4x4.
Ellis makes a superb product for a fair price. When I was jacking my building, I never had any concerns about its quality or strength. The only thing I have to complain about is where the 4x4 is parked.
The screws in the inside of the product have very sharp points. I will purchase more products from Ellis with complete confidence that they will do the job I ask of them.
