Basic Door Installation
Step 5
Cute WRB at corners to allow
folding back and taping about 6”,
exposing the flashing as shown.
Place a bead of caulk down the
jamb face and across the face of
the header to allow the mounting
flange of the door to rest against
this sealant.
Step 6
Place mounting flange of door
against the caulk/sealant as the
door is placed in the opening. Do
not put sealant across the sill pan
because the pan needs to able to
drain outward any wanter that
gets into the cavity.
If the door is being mounted
through the flange/fin, use
Simplex nails or similar to be
sure that the flange/fin can
expand and contract without 
disturbing the flashing or the
seal.
Place drip cap over the top of the
door to direct water out to the
sides. If possible, bend the hori-
zontal member of the cap down at
both jambs as shown.
Simplex Cap Nails OVER fin allows
frame to move better than nails
through mounting slots
