The 30-919 is only available in black. The black finish was added to the
spring plate by the manufacturer because it has an ingredient that
makes it possible for the furniture manufacturers to powder coat the
chair frames after they are assembled. The black finish will hold an
electrostatic charge that attracts the powder. You can spray paint the
plates with aerosol paint from a local paint or hardware store. You
should be able to find an aerosol paint that will come close to matching
the original considering most of the spring plate is not exposed.
Fiberglass Rocker Springs 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 (Please see video below). 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.
