The marine 4 inches screw-in deck plate is designed with a rubber O-ring that creates a watertight seal for safety. In addition, this particular plate style has a single-start, non-jamming (no cross-threading), extra-strong, self-cleaning buttress thread. This Five Oceans Screw out Deck Plate is great to use in the marine environment.
We take enjoyment in the products we make and guarantee the buyer that all Five Oceans products are ready to handle the extreme conditions of the open sea or terrain. However, we also know things can happen that's why we've got you covered for a year.
