Review on 🔌 LINKSOLAR Weatherproof ABS Solar Double Cable Entry Gland with Curved Cable Connector - Ideal for Rv, Campervan, Boat (Type D, Black) by Jason Bolden

A bit pricey for a piece of plastic but overall well thought out. Note that double-sided tape and/or mounting tape is probably not sufficient to hold it in place against the pressure of wires or cables entering or exiting the unit. Don't worry I drilled four mounting bolts to mount it securely to the roof of my fiberglass van and this with mounting tape and roof seal made it tight and watertight. To reduce potential water leaks, consider drilling separate, narrow holes for each of the two cables or wires to pass through the roof surface, rather than one large hole for both cables to pass through together. I recommend this product.
