These watertight, non-opening, fixed ports are designed for light, or viewing, only.
The construction of these fixed ports is based on Beckson's corresponding size of deck plate.
A watertight, permanently bonded acrylic lens is substituted for the deck plate lid.
Although watertight, their lightweight construction makes these deadlights most suitable for interior applications, such as doors, lockers, and interior bulkheads.
As with deckplates, they also find use in non-critical exterior applications.
Trim rings are available by special order, please call
The 4" size (only) is available in beige by special order, please call
Size is the nominal size of the lens; see the Spec Table for a full listing of all dimensions
