latch jamb leg in a square position. It is
recommended to place a minimum of three
shims between the stud and the jamb leg.
Remove the Q-lon Weather stripping and
temperately fasten the jamb about 2” from the
top and from the bottom in an area that once
the Q-lon is reinstalled will be covered with # 8 X
3” Drywall Screws. When installing a single door,
do not shim and fasten the top of the unit. If you
are installing a prehung unit that has sidelites,
shim and fasten the top of the unit where the
sidelite joins the doorjamb.
10. After rechecking that the hinge jamb is still level
and square, secure the jamb leg in place. Make
sure that the door opens freely and the space
between the door and the jamb is level on all
sides. Be sure that the Q-lon meets and seals the
door on all sides evenly, so when closed no light
comes through. Adjust if necessary. In case of
adjustments, loosen or remove the latch jamb
fasteners and adjust the latch jamb until there is
even contact with the weather stripping.
11. Reassure that the door shoe touches the
threshold evenly. Most doors have an oak
adjustable aluminum threshold; in this case, you
can make corrections by adjusting the
adjustment screws on the top of the oak strip.
These allow you an adjustment of maximum ¼”;
in addition to the adjustment at the threshold,
you can lower the door sweep by 1/8” by
loosening its screws and pulling the door sweep
down.
If you have ordered the unit with a solid oak sill,
you can adjust the threshold contact by
adjusting the squareness of the door unit and
lowering the door shoe.
12. Recheck for smooth operation and even
spacing between the door and the jamb.
Secure the latch and the hinge jamb in place
13. If you have a double door. some additional
fastening is required. Double doors should be
secured through the jamb head and into the
door header with two 10D finish nails or two # 8 x
3” drywall screws. DO NOT SHIM THE TOP OF THE
JAMB HEAD!
