<p>This heavy duty fiberglass rocker spring plate measures 2 1/2" wide x 5" long x .25" thick and can be spray painted.</p> <p><b>How To Install</b></p> <p>Before replacing the rocker spring plate, closely examine the assembly of the rocker spring plate, reinforcing metal strap, nuts and bolts. The head of the bolt and the nut should never be installed directly against the rocker spring plate. (Bolts, nuts and reinforcing metal straps not included; re-use those from your swivel rocker.)</p>
