Watertight Inspection or Access Port Deck Plate 4" White Screw-In SeaDog Line

I replaced older deteriorating plates and these were a perfect match. Excellent quality at a very good price.

Specs on size correct. Seems to screw/unscrew smoothly, and ridges on underside keep adhesive spread well. Be careful not to screw too tightly to hull -- looks like two of the screws I put in stressed the plastic which looks like it may crack at these stress points over time.

Replaced those old cracked ports perfectly

Couldn't find a screw-in 4 inch access plate locally - this one fit the bill perfectly. It shipped quickly and worked perfect.
