B height

A professional from California says:
Have you installed screens using this guide for the "B" type door? I've always deducted 1/4", not added 1/8". Even deducting 1/4" the door is often too tall.

Dave from SWISCO responded:
Hello! Always good to hear from you. Are you referring to the "B" measurements for the "U" type door? If so, what we would do would be to deduct 1/8" from the tightest measurement of the track, measuring in three places: each end and in the middle.
