The EZ Frame Braces by Swing-N-Slide can add additional support to the A-frame construction of your wooden swing set. This set is designed to diminish the side-to-side motion while kids are swinging. Each set includes one pair of green powder-coated braces for both the left and right sides. These braces easily install with the help of the fully illustrated instruction manual. Carriage bolts, screws/nails, and lumber are sold separately. Each Metal Brace is 19.25" in length and 6" wide.
