SEAVIEWRound Cable Gland | Marine Grade Waterproof Cable Pass Through Cable Clam | CG20PG - Grey Plastic

These simply do not last. I had mine installed for for less than a year. They are made from the wrong kind of plastic for outdoor use. The grey outer cover is cracking and now I’m worried it’s going to leak. The worst part is the wire is inaccessible and now it’s going to be a total nightmare to replace. Stick with a brand like BlueSea. Regretting buying this now.

Easy to use, it comes with little copper tubes that work incredibly well for drilling holes in the rubber grommet, I’ve actually used them a few times on other things now as well. I also like that the cover and the seal part fastens to a base plate. If you need to make changes to what goes through the seal you don’t have to re-bed the base plate because it attaches separately. Seems like a quality piece.

I used this to implement an attractive and water tight cable pass-through into the house. Although pricey, it looks really nice and professional. Much better than a drilled hole for the cable and globs of silicon sealant.

AAA+ PROMPT PROFESSIONAL SERVICEPerfect water tight gland for my custom portable Humminbird Helix 7 MEGA DI GEN4 fish finder GPS System. Only had to drill 1 small hole for the wire pass through. Simple installation instructions to guide you through for first timers.

So glad I found this product to install a water proof cable in the roof of my motorhome
