The Australian Trellis Door Company (ATDC) recently installed their S04 double diamond doors to secure the shopfront at Trek Bicycles in Richmond near Melbourne.

These shopfront doors are unique in that they retract sideways out of the way when not in use and can also hinge out of the way completely in the folded back stacked position so as not to obstruct trade.

ATDC’s S04 double diamond doors allow emergency keyless egress where required. The door’s unique construction also makes it difficult for an intruder to reach through the screen to steal merchandise.
