I wanted a BIG entry door for my new shop—at least 4/0 x 8/0—so I wouldn’t have to fight carrying materials into the shop. Sure, I installed a 12-ft. wide custom roll-up right next to the entry door, but I open that ‘garage door’ rarely, especially in January, February, August, and September, and barring a big order of sheet goods, I open the roll-up door just to take finished projects out of the shop. But the main door I’d be opening every day, all day long, and I knew I would never find the door of my dreams on a shelf at a store. So I built the door and the jamb myself, as one big pre-hung unit.
