Concertina doors from The Australian Trellis Door Company (ATDC) offer a handy solution for securing benchtops, countertops, serveries, bar tops, reception desks, canteens and more.
ATDC’s concertina doors are designed to serve a multitude of quirky commercial security applications including those with curved apertures and openings with no available headroom.
ATDC recently installed a special gold powdercoated concertina door at Union Street, Pyrmont near Sydney. The door achieves lock-up by traversing a standard 600mm radius turn. A series of intermediate up/down locks allows the user to achieve seamless lock-up without the use of any floor track.
These concertina doors can also span an unlimited width without the use of any cumbersome removable mullions.
