(Fig. 15). Mark exact location of sill on floor for construction adhesive and future
fit, then remove unit.

A. Sidelight top, bottom and side edges must be sealed before installation into
the jamb.
B. Insert sidelight into the jamb in the direction as marked from the factory.
Sidelight for hinge side has pre-drilled pilot holes for hinge screws. Check for
fit, then remove.

around the sidelight of the jamb. Once the door is completely installed, the
finished trim strip may be applied with a 1-1/2" 6d finish nail. (See Fig. 16.1
for details.)
C2. For Custom Wood Doors: To weatherproof sidelights, apply a bead of
caulk along the inside rabbeted corner the entire length of the sidelight jamb
leg, sidelight mull post, sidelight head jamb, and sidelight sill (Fig. 16).
D. Insert sidelights back into jamb.
E. Use bar clamps to tighten jambs to sidelight.
F. Anchor jamb leg to sidelight through back of rabbeted portion of jamb with
1-1/2" screws at top, bottom and center. More anchor screws may be
necessary on larger sidelights (Fig. 17).

hinge (Fig. 18).

1-1/2" finish nails approximately 2" down from head jamb through rabbeted
face of jamb. Anchor bottom of mull post to sidelight using two 1-1/2" finish
nails approximately 2" up from sill into rabbeted portion of mull post.
