Roller door sizes for Bathurst garages
Roller doors come in size bands rather than one size fits all. Steel-Line sorts its residential range into an "A" series for openings from 750mm to 3430mm wide and an "AA" series from 3435mm to 5500mm, with a light industrial "B" series from 2855mm to 5500mm for bigger sheds.
The roll also needs room beside the opening. Steel-Line's figures are 90mm of side room for a hand-operated "A" series door and 120mm once an opener is added, rising to 125mm and 150mm on the wider "AA" doors.

Seals along the bottom and sides
Steel-Line fits a PVC weather seal into the aluminium bottom rail of its roller doors and offers a brush seal for the side guides as an option. Seals help with dust, leaves and draughts, though no seal makes a garage floodproof.
The NSW State Flood Plan says floods around Bathurst can rise and travel quickly, so if the garage sits low, keep stored things off the floor rather than counting on the door to hold water back.
Choosing a motor
Merlin's roller door openers are the SilentDrive Essential, the WeatherDrive and the SilentDrive Elite, and of those Merlin lists only the Elite as compatible with battery backup. Steel-Line says its roller door opener has F-linX Wi-Fi for phone control and suits single or double doors up to 16 square metres.
In NSW, plugging a motor into an existing power point is not electrical installation work. If there is no point near the roll, a licensed electrician adds one.
Using the manual release safely
On a roller door the opener sits at one side of the opening with its release cord attached, Merlin says. Pull the cord down firmly once to disconnect it, and never try to haul the door with the cord itself, which Merlin warns will snap under the load. A door with weak springs can fall fast once released.

Sheds on bigger blocks
For a wide shed opening, ask whether an "AA" or a light industrial "B" series door suits the span.
Bush fire prone land
The RFS says building on bush fire prone land may mean changing construction materials, so check your block's map before you order.
No wiring licence, no wiring
NSW needs an electrical licence for any wiring work, whatever it costs, including a new power point for the motor.
What we would do
Measure the opening and the space on both sides of it before you ask for quotes. If one side has less room, say so, because the motor usually goes on one side and needs the extra space there.
