longer than the opening width. Apply at the bottom of the
opening as shown (1E) so it overhangs 1" to the exterior.

will extend 6" up each side of the opening.

A. Install and level sill spacers. Place 1" wide by 3/8" thick spacers
on the bottom of the window opening 1/2" from each side.
Spacers are also required at points where windows are joined in
multiple window applications. Add shims as necessary to ensure
the spacers are level. Once level, attach spacers and shims to
prevent movement.
Note: Improper placement of shims or spacers may result in
bowing the bottom of the window.

them and store them in a protected area.
