Power Post® – Adjustable Crawl Space Support Jack

Description

Is your floor sagging? Do you have a bouncy a floor? Install a granite-topped island in your kitchen? Adding a large bathtub on the second floor? Are you installing a heavy fish tank in your home and concerned you can’t support the weight? There are hundreds of reasons why DIY projects include the need to install additional support for the floor above your basement or crawl space. The Power Post, adjustable crawl space support jack, makes adding floor joist support easy and permanent. With two bottom plate designs, you can install them using pre-cast footer blocks or poured-in-place. (Check your local building code for specific footer requirements in your area.)

The Permanent Solution to Fix Warped & Sagging Floors

Don’t jack-up your house using a temporary solution! Use the Power Post because doing it right, and meeting building code, is the smart way to go. Made of galvanized steel, this post system will not rust and will not need to be replaced. Each kit comes complete with mounting hardware.

Built to Stabilize Your Crawl Space

Designed by a team of Structural Engineers to meet/exceed residential building codes the system is simple to install and completely customizable. (This is not a temporary jack.) The tube steel can be field cut to meet your exact needs and the adjustment screw provides a range of 4 inches to fit and adjust your column for the perfect level of support.

Easy Install Joists Support

Installation is as easy as one, two, three. Step one: drill your precast footer block or your poured-in-place footer and mount the base plate using the Trubolt anchor wedges (included). Step two: set it plumb and snug against the beam, attaching the top plate to the wood beam with the provided hardware. Step three: make your final tension adjustments. Done!
