New Arrival Coming Soon! Expected availability is May 2011.Designed with an extra-heavy O-ring for a watertight fit, these pry-out plates have nonskid surfaces for horizontal installations and smooth surfaces for vertical installations. The diamond pattern deck plates have a nonskid surface that extends across the center, eliminating the edge ring that traps dirt and debris. The clear center plate permits observation of controls or gauges without the need to remove the plate. Clear plate models include white flange rings. Pry-out plates should not be installed where internal pressure (oil canning) is present.
