Stop in for a cup of coffee
When we put in our containers at the rock farm they were on concrete. We built steel ramps to access the open end and used expanded metal for better traction on the ramps. The wiring we left to our electrician wizard, they have knowledge of all sorts of conduit clamps and their uses. Pretty sure he used Unistrut in many instances. I know the power supply was underground at one end and I think he used flex conduit to get inside with a coupler made for going through metal like a breaker box. Fore I fergit :lol: for the ramp install, make sure on the clearance for the doors.
