Technical Specifications

The frame of your existing window must be square, plumb,
and level for the new unit to be properly inserted into the
existing frame. The opening also must be structurally sound.
As you measure, remember:
All Crestline Replacement Windows are custom-built.
Round your measurements to the nearest 1/8”. Always
use the smallest width and height measurements for each
window you plan to replace.
1. Measure between side jambs at top, center, and
bottom. (See Figure 1) Record this dimension as "Width".
If opening is uneven, record smallest dimension.
2. Measure height of existing frame at left, center
and right. (See Figure 2) Record this dimension
as "Height". If opening is uneven, record smallest
dimension.
3. Order unit by stating width rst, then height.
Be sure to double check your measurements or have
another person verify your measurements. Inaccurate
measurements could result in a window that will not t into
the existing opening. Because all Crestline Replacement
Windows are made to your specications, they are not
returnable.
IMPORTANT: 1/2" will be deducted from the width and
height given for Select 300 units & 1/4" in width and 1/2"
in height will be deducted for Select 200 units during
manufacturing. This allows for proper squaring and
shimming during installation.
Remove old window sash and stops. Insert new replacement window. Fasten to existing frame, caulk and seal.
