U.S. door’s legendary Model 501 Roll-Up steel door is the standard of the self-storage industry. Self Storage SystemsThere are more Model 501’s currently in operation than any other competitor’s single roll-up door model.

That’s because the Model 501 has improved and evolved over the years, based on U.S. Door’s decades of self-storage experience.

The doors are easy to install and mount to wood, masonry or steel jambs, with sizes as large as 10’ (3048 mm) wide by 10’ 93048mm) high and optionally can meet wind loads of up to 140mph.
