Pleased with product and shipping
The cabinet has a removable backplane (panel) to allow for installation of equipment, in my case a solar charger and circuit breakers. This makes installation and servicing easy as you can remove the entire back panel to work on equipment. There are two 1/2" diameter knockouts on the bottom of the box for electrical connections to the solar panels and equipment. The cabinet is well constructed, very sturdy and has mounting tabs on both top and bottom that will allow for various mounting configurations. The gasket on the door seals well and all the louvered vents are screened on the inside to keep the bugs out. The door latch can be locked with a long shacked padlock. Shipping was good. It actually arrived a day ahead of schedule. All in all, I'm very pleased with the cabinet. I had contacted a local fabricating shop to build something for me and the price was a bit more than this cabinet without the door and louvers.
