Review on CARMTEK 50 Amp RV Outlet Box - Lockable NEMA 14-50R Outdoor Electrical Box for RVs & Trailers by Richard Counts

The box itself is very sturdy and looks nice but that's all I got for it.1. The box is very tight when working with 6 gauge wire.2. The screws for attaching the wires to the back of the connector go through the center of the cable entry connector meaning you will need to separate the wires to fit.3. The wires never get fixed and I ended up stripping the screw heads when trying to tighten the wires4. There are no knockouts. They look like knockouts, but they're not. You will need a hammer drill or multi-purpose drill to open the access holes. After 2 hours of unsuccessful attempts to secure the wires by stripping the screw heads, I threw this piece of junk back in place. Into the trash. I then went to Lowes and bought a $30 Eaton 50 amp RV box and installed it in less than 10 minutes. I do NOT recommend this product.
