John's videos show how he set-up his CoopBoss, but my implementation was a little different in that my coop door was on a side wall rather than a floor. I live in the Pacific Northwest where there's a lot of rain that can warp outside wood doors, exposed to the elements. So while my coop door is relatively protected from the elements, the moisture in the air alone is enough to cause plywood to warp and potential cause issues with the opening/closing mechanism. I've attached some pictures so folks can see how I built mine - the door is actually an $11 poly cutting board (1/2" thick) - so the sides are nice and rounded there's no chance of warping. I used aluminum 'h' channel for the slide guides and the combination works perfectly. This should last as long as the CoopBoss...
