Step 5: Shim at Hinge Locations and Secure Hinge jamb.
Leave door fastened and closed with transport clip.
Shim above screws, behind each hinge location,
between the opening and the jamb.
Use a 6 foot level and re-check hinge jamb to ensure it
is plumb and straight.
Finish driving screws tight in the middle first then top
and bottom last.
Step 6: Adjust Rest of Frame and Fasten.
From the weatherstrip side of the door, check
weatherstrip margins and contact.
Make frame adjustments so the weatherstrip
contacts the door surface equally at the top,
middle and bottom, an even 3/8 inch to 1/2
inch when fully closed.
Secure the lock side jamb with #8 X 2-1/2 or 3 inch screws through the pre-
drilled holes at the top and bottom. Do Not drive screws tight at this time.
From the swing side of the door, shim above the screw locations and make
adjustments so the margins between the door and frame are even top to
bottom.
Note: For Double Doors, make adjustments that effect the alignment, margins
and weatherstrip contact between the doors. Also follow the Astragal Site
Package Instructions for details on properly setting the slide bolt hole
locations.
Step 6 cont: Adjust Rest of Frame and Fasten.
Re-check everywhere for plumb and square, and an
even weatherstrip contact.
Finish driving all screws tight.
Step 7: Remove Transport Clip and Open Door.
Remove the transport clip.
Open and close door to check for smooth
operation.
With the door open, drill 1/8 inch diameter pilot
holes in the top hinge in the 2 screw hole
locations closest to the weatherstrip. Then, install
the #10 X 2-1/2 inch screws (provided) through
the hinge, into the stud, to anchor the door frame
and prevent sagging.
Step 7 cont.: Remove Transport Clip and Open Door.
For Sidelite and Patio Units: With the door open, check to determine if the 2-
1/2 inch long hinge screws were pre-installed in the hinges. If not, drill 1/8
inch diameter pilot holes and install the long hinge screws in the hole
locations closest to the weatherstrip.
Close the door and carefully shim between the jamb and the opening behind
the adjustable strike plate area.
Then open the door and drill 1/8 inch dia. pilot
holes and install the #8 X 2-1/2 inch screws
(provided) through the strike plate holes to
secure the lock side jamb and provide security.
Adjust strike plate in or out for proper
weatherstrip contact and door operation, then
finish tightening screws.
Step 8: Adjust Sill.
Your door unit may have an adjustable threshold cap. When properly
adjusted, it should be snug and slightly difficult to pull a dollar bill out from
under the door when it is fully closed. The dollar bill should be able to be
removed without tearing.
This check should be performed at each
adjustment screw location.
After adjusting the threshold cap, ensure that the
weatherstrip is flush with the top of the threshold
cap. Trim as necessary.
Step 9: Install Corner Seal Pads – Inswing units Only.
Apply sealant (Polyurethane or
Elastomeric) at the joint where the
threshold cap meets the door jambs.
Remove the self-stick paper from
the corner seal pads and apply to the
door jamb, with the bottom lined up
evenly with the top of the threshold
cap. When the pad is correctly
installed, the tab is on top and the
narrow part is on the bottom.
The bottom of the pad is the same width of the threshold cap to help with
alignment during installation.
Step 10: Additional Frame Anchoring.
If sill is prepared for anchoring screws, place appropriate screws through
the sill into the sub floor where needed. (Primarily on Outswing Sills)
We recommend that you provide additional frame anchoring as shown
here. Certain states or jurisdictions, notably Florida and the coast of
Texas, have specific installation requirements and may require
installation in strict accordance with the product approval for a specific
product. You should always check with the local authority having
jurisdiction for any specific installation requirements that may apply.
Specific product approval installation instructions, including those
required for the High Velocity Zone (HVHZ), are also available at
