O-ring for deck plate

Rep was very helpful with finding and ordering replacement O-rings.

6” Sure Seal Deck Plates

I ordered three of the deck plates for a boat rebuild project. I opened the packaging and had difficulty separating the lid from the base. I left a message asking that someone call me. Andrew called within a short period of time and he instructed me how to spin them apart grabbing the lid and the outer ring. Thanks Andrew I appreciate you calling back.

The product worked but it was very hard to find the right one. I only needed the cover because a mechanic left it off and it blew out of the boat. I pulled the cover off the inspection port under my console and it was stamped T-H. However, it would have been much easier to buy the correct cover plate if it had a model number on it. The mechanic tried to replace it with a pry-out model and it was wrong. Then I ordered the regular screw-in plate and it was the wrong one again. I returned that one and got the low profile one which was the one I needed. It worked great but an ID No. stamped on the product would have saved all that searching.
