The SmartJack XT system provides solid support for sagging and undersized beams, restoring stability and straightness to sagging floor joists in a crawl space.
Once installed in your crawl space, SmartJack XT supports can correct problems such as sloping and overly springy floors, interior wall cracks, and out-of-level door frames.
Because of its design, the SmartJack XTcan be adjusted over time to provide additional straightening and leveling action if necessary.
