Is a dry box dry? How to improve seal

Had a raft upside down in the Salt for maybe an hour.

Cambridge dry box leaked big time.

Is this normal for all dry boxes?

anyone know a good source for a better or thicker dry box gasket than the one supplied by the builder?

Just looking at the gasket and it seems a thicker gasket might seal better than the factory supplied unit.

It depends on the type of dry box you have, but I have had good luck using camper shell sealing tape to make leaky dry boxes dryer.

I have been building dry boxes for many years. Most "dry boxes" are not totally dry, they are like "semi-dry " boxes. Cambridge uses .080" aluminum for their boxes. In my opinion it is way too flexible and can tweak just enough to let water in, especially under pressurized water like the salt river. I have found that by using .100" aluminum for smaller sized boxes and .125" for larger boxes that the flex is greatly reduced. I have also found that by using a bulb gasket, the seal is greatly improved. I have seen this setup completely submerged (in still water) for over 1/2 hour with zero leakage. Corner gussets at the top of the box where the gasket is set makes for a nice ridius in the corner, and it stops those pesky cracks! Check out www.artisanmetalworks.net

What go big said.

If you have latches a third of the way in on a 44" box that is 15 inches or more away from support at the end of the box. Holding water out in dunk test maybe but you get it in current or pinned and all bets are off unless you go with latches every 8 or 10 inches or something.

I have had water come in after getting slapped by large waves too. Too many psi on the side of the box under the overlap to hold it out.

I love a post that sends me to the dictionary. "Cept my dictionary doesn't have these words. What's a gusset? Ridius? Seriously. Don't think I'm the grammar-police-ball-busting-turdface that usually chimes in here.

Your dictonary sucks. In the future type the words into Word, then right-click and click "look-up." You may have to correct spelling first...

Gusset (n): a flat, often triangular plate, usually of steel or plywood, used to connect and reinforce a joint where several members meet at different angles, e.g. in a pitched roof

Ridius (typo): radius (n): a straight line extending from the center of a circle to its edge or from the center of a sphere to its surface.

On most boxes, I find that unstrapping, then unlatching is a pain in the butt (or fingers as the case may be). I like to use cross straps about every 12 - 14". That saves on a lot of nicks and cuts given by those draw latches...... Thanks for providing the definitions, earthNRG!

Don't know what a gusset is? you need to get out more trollholio.
and for any spelling challenged or comprehension challenged trolls out there.
type in the suspect word and then type in websters.
it even worked on ridius.

gobig that is some nice work at your site. assuming that is all you.

you should put that link in your sig. might get you a little work.
