INSTALLATION INSTRUCTIONS CONTINUED
INSTALLATION IN A DOUBLE-HUNG SASH
WINDOW
1. Cut the foam seals (adhesive type) to the proper
lengths and attach them to the window and stool.
(See Figure 10)
2. Open the window sash and place the window slider
kit on the window stool. (See Figure 11) Adjust the
length of the window slider kit according to the
width of window. Screw down the two screws on the
window slider kit. (See Figure 11) Cut the adjustable
window slider kit if the width of window is less than
26.6 inches. (See Figure 12)
3. Close the window sash securely against the window
slider kit. (See Figure 13)
4. Drive two ½" screws to secure the window slider kit to
the window sash. (See Figure 13)
5. Secure the window slider kit to the window stool.
(See Figure 13)
A: For wooden windows: Use ¾" screws for securing.
B: For Vinyl-Clad windows: Use ½" hex head cap
screws for securing.
6. To secure lower sash in place, attach right angle
sash lock with ½" (12.77mm) screw as shown.
(See Figure 14)
NOTE: It is difficult to lock the windows with the
sash lock for Vinyl-Clad windows, so you can
use lock by window itself.
7. Cut the foam seal to an appropriate length and seal
the open gap between the top window sash and
outer window sash, as shown. (See Figure 15)
