Predrill 1/8" holes and permanently fasten 3" exterior 
grade wood screws (not included) through the head 
jamb into the frame at locations shown in Figure 2e. 
For hand stained PVC jambs, use the provided 
counterbores for predrilling countersink holes for #8 
wood screws as mentioned in previous section and plug 
the screw holes with the screw caps that are included.

Installing Astragal Retaining Plate & Grommet for 
Double Door Units 
After the double door is properly aligned, use the 
astragal bolts to mark and drill 3/8" diameter x 1 3/8" 
min. deep hole through the head jamb and 5/8" 
diameter x 1 3/8" min. deep hole through the sill, per 
Figures 2f, 2g, and 2h. Pre-drill (2) 1/16" pilot holes for 
the mounting screws for the head jamb. Install the 
retaining plate in the head jamb using the included 
hardware and insert the grommet into the 5/8" 
diameter hole in the sill.

Position Strike/Deadbolt Plates for Double Door Units 
Close both doors. Mark desired positions for strike and 
deadbolts plates. Loosen the retainer screws (do not 
completely remove screws). Place the strike and 
deadbolt plates into position (left image of Figure 2h) 
and tighten the screws. Only use the screws that came 
in the retainers. Do not use other screws as this may 
cause a malfunction in the operation of the doors. 
Check positions and adjust as needed. 
Install Trim Covers for Double Door Units 
Cut the Trim Covers so that the ends fit under both the strike 
and deadbolt plates and butt up against the strike and 
deadbolt retainers (as shown in the right side of Figure 2i 
[1,2,3]). 
Loosen the screws on the strike and deadbolt plates and slip 
the Trim Cover underneath. Snap the Trim Covers into place 
and tighten screws.

Install 2 screws at the location

Threshold 
For an in-swing door with adjustable threshold, adjust the 
threshold as shown in Figure 4 so that there is even contact 
between the door sweep and the threshold. To test, put a 
sheet of paper between door sweep and threshold, close the 
door and pull. The correct adjustment would have slight 
tension, but if the paper tears, the tension is too high.
