05 / Before you order

Measure the opening correctly

Record the finished structural opening, wall depth and floor level before confirming the frame size. Use millimeters and send site photos with your drawing.

Measure opening width at top, middle and bottom, height at left, center and right, and wall depth
01

Width

Measure top, middle and bottom. Note the smallest clear dimension.

02

Height

Measure left, center and right from finished floor to underside of head.

03

Wall & level

Measure wall thickness at several points; note floor finish, thresholds and obstructions.

Do not subtract a generic fitting allowance yourself. Supply measured opening dimensions; we will confirm frame outside size and installation clearance on the shop drawing.
06 / Opening direction

See the door from the outside

Imagine that you are the person shown below each diagram, standing outside and looking toward the room. The gold dot shows the hinge. The solid blue line shows the open door; the dashed line shows its closed position.

Left hinges · opens outwardOutside viewer with left hinges · opens outward and interior labeled above the opening
Right hinges · opens outwardOutside viewer with right hinges · opens outward and interior labeled above the opening
Left hinges · opens inwardOutside viewer with left hinges · opens inward and interior labeled above the opening
Right hinges · opens inwardOutside viewer with right hinges · opens inward and interior labeled above the opening
For a double door, mark which leaf is normally used (active leaf) on your floor plan. Send a photo from outside and draw an arrow showing the opening direction. We will confirm it on the shop drawing.
