What about a pitman arm from a junkyard truck?

Seen a few old manual steering gear boxes used as gate openers. Simple to build a salvaged garage door opener remote and circuitry 2 limit switches a steering gear box and a small electric motor with 2 sprockets for the speed reduction

wouldn't that fill with water in the rain?

Look at each top corner and you will see the studs for the cover.

In my experience any box below grade even with a "water tight" cover will fill up with water.

Have you by any chance experienced the wonders of modern polysulphide adhesive sealants? : ) Looking at the video the box is above ground level but perhaps a good few Silicon absorbent sachets tossed in before sealing would not go amiss huh?

Anything underground.....ANYTHING underground WILL fill up with water.

Even underground conduit requires use of waterproof cable.
