About this item
- Level Uneven Floors With Just A Twist -- No complicated tools required! The easy height adjustment (0.6" to 0.8") lets you fine-tune the support to lift and level even the trickiest uneven floors. Whether you’re fixing a single spot or reinforcing a whole room, it’s quick and hassle-free.
- Fix Sagging, Bouncy Floors For Good! -- Tired of walking on floors that feel wobbly or sink in the middle? This heavy-duty support block holds up to 5800 lbs, giving your weak floor joists the rock-solid lift they need to stop sagging, squeaking, and bouncing. Perfect for DIY crawl space floor repairs.
- Fits Most Floor Joists & Beams, Easy To Install -- Designed with a wide, stable base and a simple mounting bracket, this support block fits standard floor joists and beams. Just set it in place, adjust the height, and you’re done – no fancy carpentry skills needed for a professional-level floor repair.
- Stays Put, No Slipping Or Shifting Under Load -- The interlocking design locks everything in tight, so once it’s set, it stays put. No more worrying about your support slipping out of place or loosening over time – your floor will stay stable and level for years to come.
- Built To Survive Tough Crawl Space Conditions -- Your crawl space can be damp, dusty, and full of temperature swings – and this support block is made to handle it all. It works reliably from -22°F to 230°F, so you don’t have to worry about it warping, cracking, or failing down the line.
