Nice House jacks
Size: 4 Pack (11"-17") Color: Orange
House jacks are built, nice nice and easy to work with top plates swivels so has your tightening it up you don’t have to worry about it moving

Reasonable price, easy to use
Size: 4 Pack (11"-17") Color: Red
I bought these to help level and support a tiny house and they work perfectly for the job. They are built very well and function as they should. The pads are a decent size to maintain a good stable footing, and have holes to allow anchoring to whatever surfaces you are placing them on. They come with solid rods that allow you to adjust the height of the jacks by turning the adjustable screw. These are not loose/floppy like some others that I looked at, and don't feel like they'd just fall over if you leaned on them. I would recommend these to anyone that needs leveling jacks for an unstable foundation, or adjustable piers for a deck, or even a shed or other building. I will be ordering more of these to place in other positions under the house to create a more solid foundation versus the "blocks" the building was initially set on. These will allow for adjusting for any future sinking or flexing of the structure due to age, or settling of foundation, which will be very useful. Say goodbye to squeaky floors! ... show more

Very easy to use.
Size: 4 Pack (11"-17") Color: Black
These were perfect for supporting patio deck. Easy to set up and with the pivot to support bracket and bar for turning Jack screw, it makes it effortless to level the deck with ease. Used a little grease on Jack screw and taped over bar hole in screw to keep them from rusting.
