If you're doing any kind of renovation, floor leveling, or just need some serious temporary support, these TOPTGO Floor Joist Jacks are exactly what you need. They come in a handy 2-pack, and each one can handle up to 4400 pounds—so they're no joke. Made from high-strength steel with a powder-coated finish to resist rust, wear, and impacts, whether you're using them indoors or outside. The height adjusts smoothly from 19 inches all the way up to 36 inches, so you can get the perfect fit for supporting joists, beams, ceilings, porches, decks, or even basement crawl spaces. The top plate is 5x5 inches, and the base is 3.5x3.5 inches, with deep embossing to prevent slipping or denting. Assembly is straightforward: just use the two included bolts and nuts to lock in your desired height, and the horizontal bolt adds extra stability to keep everything safe and secure. They're tight-fitting so there's no wobbly lateral shifting. Super useful for DIYers, contractors, or homeowners tackling projects like sagging floors, stair repairs, or adding structural support. Lightweight enough to move around but tough enough to do the job right. Keep a pair in your workshop—you'll be glad you did when a support project comes up!
