Fiberglass Rocker Spring Plates do not have holes drilled. You will need to use the old spring plate as a template to measure and drill hole to fit your furniture. It is suggested that you use a drill press to make sure the holes are straight. Re-assemble the parts the same way that you took them apart. There should be a metal plate or washer between the bolt head and the spring plate.

Spring plates can also be spray painted to match the color of your patio furniture. (Drills and Spray Paint not included with this product.
