🔒 Waterproof Adjustable Protectors with Conextlink Firewall Function Review

It wasn't the size I wanted and the website didn't list the size. It was too big for the hole I wanted to use so I had to go and buy another one.

Bought and it was too much for what I needed. I had the correct caliber size, but the part itself is too bulky. I tried to return it, I got no response from the seller.

I was building a small off grid solar system (in a box) and needed some waterproof grommets to get the solar panel cable into the box. This product worked great.

I was building a small off-grid solar system (in a box) and I needed a pair of waterproof grommets to run the solar panel cables into the box . This product worked great.

I bought these (size 1/0) thinking I would be running 1/0 wiring all over my Ford Expedition. Shortly after receiving them, 50 feet of 4/0 weld wire fell into my lap. I decided to see if they would work with 4/0. They do. A bit tight but once you start the wire slides easily through the grommet.

I'm doing some 2/0 runs of wire from the alternator to the batteries, 4 runs. I had to drill a 1 1/4 inch diameter hole to use this item. Make sure the surface is flat or you won't get a strong seal. Also attach them before threading the wire. It is difficult to tighten the nut on the firewall with the wire pulled through. I would buy again if I need more. They are larger than other 1/0 firewall stubs.
