Complete Your Purchase
A rubber O-ring on these plastic deck plates creates a watertight seal for safety.
This screw-in style deck plate is engineered with a single-start buttress thread that is extra strong, self-cleaning, and designed to prevent cross-threading, making it simple to open and close without jamming. Built from durable UV-resistant ASA plastic on West Marine–manufactured models and rigid ABS plastic on Beckson-manufactured models, it offers long-lasting reliability even in harsh marine environments. Installation is straightforward using #8 pan head screws or through-bolts (sold separately). For the best seal, use only 100% silicone caulk. Backed by a one-year warranty, this deck plate delivers dependable performance and ease of use on any boat.
