Installation in a Double Hung Sash Window
Step 1
Cut the foam seal to the proper length and attach it to the window sill, and window frame as
shown in the image to the left. Your window kit includes four (4) adhesive backed foam strips for
this step, two that are short and two that are longer.
Step 2
Attach the window slider kit to the window sill. Adjust the length of the window slider kit
according to the width of the window. Use the window slider “bolt” to secure the slider to the
correct width. Open the window sash and place the window slider kit on the window sill then
close the window sash securely against the window slider kit.
Note: If desired, you may choose to attach the adhesive foam seal to the window slider kit instead
of the window sill and frame.
Note: If needed, you may trim the adjustable window kit if the width of the window is less than
26.5”.
