A big advantage of the DBCI door is its open barrel design. Thanks to the exposed axle, all the door components can be checked or cleaned at any time. This makes repair and maintenance easier for self-storage owners. Simple tasks, like applying lubricant or changing out a spring, can be accomplished faster and at less expense without inconvenient obstructions. At DBCI, we don't just think about building a quality door. We think about building it to meet all our customers' needs.
