Is there a standard method or product for punching a low-height cable access hole through a car roof, and keeping the wind-blown rain, snow, dust, etc out?
I would like to feed about six to eight 3-5 mm cables for waterproof cameras from the roof rack into the cabin, and to be able to go back and make changes later. I don't want just a big glob of sticky messy caulk squished into the drilled roof hole.
I am thinking something made of of plastic, and shaped like a short mushroom stem and cap might work to pass cables and keep out water, but I am not finding anything like this in my web searches. I have no idea what it would be called or who would sell it.
