Roller Doors – ordering width questions.
For Series A domestic door openings up to 3m wide you should add 25mm on each side for the tracks, Eg. if your framed opening is 2.8m you should order a door curtain 2850mm wide. If your opening is 3m you should order a door curtain 3050 wide.
For AA extra wide domestic roller door openings over 3m wide up to 5.1m wide, you should order 50mm on each side for tracks. E.g. a 5m wide opening order for a 5100mm wide curtain, and for a 4.2m opening order a 4300mm wide curtain.
For any series B light industrial doors, there are large tracks needing 50mm of the curtain on each side. So order 100mm wider than the opening. E.g. 4m wide opening, order a 4100mm wide curtain. 5m opening, order 5100mm wide curtain.
