Deck gland screws leaking

I was wondering, when putting in a deck gland to run a coax cable through the deck, do the screws that hold the gland in ever cause water to leak into the deck, and water log the deck??? How can you prevent that from happening?

There is a ton of information about how to install new equipment to a cored deck. What it comes down to is that youMUST seal the core in a permanent way, usually by removing a substantial amount of the core and replacing it with an epoxy based filler. Drilling an oversized hole, filling it, then redrilling it is the usual procedure. Do a quick search, and you should get more info.

Re: Deck gland screws leaking

If you just talking about the fasteners, any good caulk will work, Polysulfide, polyurethane, or butyl. Cover the screw threads and fitting base and install making sure caulk squeezes out all around. The rout out the core and fill with epoxy routine is for fasteners that take a load. The epoxy sals core and is a solid non compressible core so you can't crush the balsa. Doesn't hurt to do it but it's a time consuming process. Just Epoxying the core with a resin soaked Q tip would be enough protection for wire glands.

Every hole in a cored deck should be treated like Maine Sail's article. Relying on caulk is just setting yourself up for big repair troubles later on.
