Measuring For a Sectional Garage Door

When measuring for a garage door, it is important to take several measurements inbetween the width and height of the garage opening utilising the smallest measurements when it comes to the ordering sizes. The ordering size for sectionals is the door size inbetween the frame legs and head section, the frame legs and headroom must be taken into account. Please see below specifications for the different types and diagrams to assist.

Sectional garage doors can be fitted behind (maximising the drive through width and height) or inbetween (maximising the depth of the garage) the garage opening. If fitting inbetween the opening, a special anchor set and frame cover profiles are required. The sectional doors come back into the garage and any obstructions must be accounted for.

Things to consider when ordering your sectional garage door:

  • Application – behind or inbetween the garage opening
  • Headroom
  • Sideroom
  • Depth of garage
  • Manual or automated
