Silicon caulk and silicon rubber caulk are actually the same product. It
will do what is needed for the size hole you have. In fact, it will work
just fine on holes much larger as long as there is something behind it to
support the mass while it cures. Allow 24 hours for full cure. I wouldn't
get a full size caulking gun tube of it, however. Go to the local auto
parts store and get a tube of silicon rubber adhesive (again, the same
product)or RTV (Room Temperature Vulcanizing). About the size of a tube of
toothpaste. Comes in various colors, too. No preference here. None of it
is UV sensitive.

Subject: [Force 12 Talk] Weatherproofing 40 mtr switchbox



I have a Force12 40 mtr switchbox that will mount on the boom of a Force12
C4S. The plastic box has a door and a separate 7/16 inch hole drilled on one

side of the box to allow entry of a cable to energize the 12 volt relay.

My question: what is the best way to weather seal the 7/16 hole ?
I have thought of using 'coax seal' or 'silicon calk' but 7/16 inch
seems like a large area for this type of product. I believe Force12
instructions call for silicon calk. This does NOT seem to be a good
solution. The correct size rubber grommet seems hard to find
and will probably not do the job. I also saw 'silicon rubber calk'
but not sure if this could be used.

I attended a hamfeast this weekend, visited Home Depot and a local
Farm and Fleet but still no solution.

Any ideas ???? Has anyone solved this problem? Maybe a hole should be
drilled on the bottom of the box to allow moisture to escape in addition to
the weather seal.

Best,

Joe - K9DMV
