What is the frame upstand size?

The frame upstand, or profile upstand size is the height of the ‘step’ between the frame edge and the sash edge that a flag hinge needs to clear in order to fit correctly.
As most flag hinges are adjustable they can be adjusted from a minimum to a maximum upstand size, commonly around 15 mm to 23 mm.

Check that the hinge you are purchasing is suitable for the frame upstand of your door.
