Review on 🔌 Versatile Solar Double Cable Entry Gland for All Cable Types - Ideal for Solar Projects on RVs, Campervans, and Boats by Micael Casillas

Not sure how long the rubber pad will seal in moisture. When installed, it will expand and pop out if overtightened (even by hand). I had to loosen and retighten to find optimal tightness before it moved. It may be necessary to replace the gasket with a better one or simply apply sealant around the entire cable entry. The rubber rings that seal the cable don't feel very tight as I was still able to move the wires back and forth with enough force. However, it rained a few days later, no leaks were found, so it does the job for now. hope it lasts There were no instructions or materials for installation. I used butyl tape around the base and drilled 4 sheet metal screws and then caulked the edges and screws. It would be easier to tighten the nuts before installing the box. I made the mistake of installing the box first and then needed someone to help me hold the nut inside to screw in the connector from the outside.
