We all worked some, and got the door made, the railing up, the door attached to the sliders, then lifted the door to get the sliders into the rail. A few adjustments, and it's done. It was a LOT of work, and expense, but it slides real easy, and looks nice. I can't really say it's worth the expense on the building we're using it for, but at least Dh learned how to do it, which is what he wanted. For a barn, nice large storage shed, boat house, etc., I'd highly recommend that type door. For a pump house, or smaller shed, not so much. It's overkill. Next job is to paint it.
