Is your sliding screen door dragging or wobbling? This corner bracket assembly is probably what you need to fix it! It's a heavy-duty replacement part used by a lot of door manufacturers. The bracket itself is made from a sturdy metal-iron alloy and measures 2 3/4\ L x 2 3/4\ H. It comes with a 1-inch wheel – you can choose stainless steel (super durable) or nylon (quieter). There's even an adjustment screw so you can tweak the fit and get that smooth, quiet slide back. Fits doors with a 45-degree miter cut. Installation is pretty straightforward – just swap out the old, worn bracket. Give your patio door a new lease on life without replacing the whole thing!
