The recommended headroom for our roller doors is 360mm. For garages with restricted headroom, our mini-roller door may be the answer. With all the same great features as our standard sized roller doors, our mini-roller can fit in as little as 230mm headroom (you’ll need 300mm headroom if you require full drive-through opening height). The mini-roller options available at no extra cost in both Roll-A-Door® and RollOver® ranges up to 3048mm wide x 2134mm high. Mini-rollers are not suitable for remote control automation.
