Screw-Out Deck Plates
Though deck plates are no new invention, Beckson was the first to conquer all three safety features and provide them here. First, ensure the cover would not open unexpectedly. Second, maintain maximum water tightness. Third, prevent jamming closed or cross-threading that would prevent a cover from being closed.
Replacement O-ring gaskets are also available and sold separately - See Sku# WBORG.
