Great quality.

So far definitely work as described. Only down side is the size of the hole you have to drill but it is what it is.

Well made with good hardware included. Have purchased at least 5 of these. Use them for solar energy storage, custom battery boxes.

Good construction, materials. I needed to get through a camper's firewall and these were two of the plastic threads too short. Had to spend an hour each one to modify the opening and the bolt. Probably deserves five stars, but all that work due to length had to be acknowledged.
