STEP #8 INSTALL DOOR HEAD SUBFRAME
Unless a concealed overhead closer is used, a subframe will be required at the door head. See the de-
tail below for the optional door header for concealed overhead closer applications.
A. The subframe at the door head is cut to run between the vertical subframes. Apply sealant
to each end of the subframe. Set the subframe into the opening at the door head, making
sure the leg of the subframe is in the glazing pocket. Pull the subframe toward the face of
the door head, making sure it is flush with the exterior.
B. Match drill the door head, and fasten the subframe as shown in the detail below with a
fastener spacing maximum of 12” on center. Refer to the approved shop drawings for fas-
tener types.
C. Tool the sealant at each end of the subframe, and remove any excess sealant that remains.
