Is your heavy wooden or metal gate starting to sag and drag on the ground? This spring-loaded gate caster is the perfect fix! It's a heavy-duty 4-inch wheel housed in a black, powder-coated steel bracket with a built-in shock-absorbing spring. As your gate opens or closes, the spring automatically compresses or extends to keep the wheel in contact with the ground, even on uneven surfaces like grass, gravel, dirt, or asphalt. This takes the weight off the hinges and posts, preventing further sagging and making the gate much easier to push or pull. The wheel itself swivels 360 degrees for smooth maneuverability. It's rated for up to 220 lbs per wheel, so it can handle most residential gates with ease. The kit includes the caster, mounting bolts, nuts, and washers. Installation is pretty straightforward – you just attach it to the bottom corner of the gate on the hinge side (you might need longer bolts for very thick gates). Say goodbye to scraping, lifting, and struggling with your gate!
