Standard Measuring Procedures
Inside (IB) Mount
- Be sure the window opening is
deep enough to install the mounting
bracket. Refer to the Mounting
Charts for recessed mounting depths
for each product.
- Measure the width inside the
window opening at the top, middle
and bottom. The top measurement is
critical because the headrail must
fit. The top measurement should
always be the ordered width.
Vertical applications require a top
measurement only;
middle and bottom
measurements are not required.
- Measure the height inside the
window opening at the left, right
and center.
- Measure the window on the
diagonal. If the 2 diagonal
dimensions are not exactly the same,
it may be necessary to specify an
outside mount for optimal light
control and privacy.
- The ordered width should ensure
a precise fit for the headrail and
allow proper operation of the shade.
If widths in the window vary, order
the minimum width necessary to allow
the shade to go up and down.
- The ordered height should ensure
clean operation at the base of the
window as well as provide maximum
privacy and light control. If
heights in the window vary, order
the shortest height for vertical
treatments and the longest height
for horizontal treatments except
Silhouette„ and Nantucket„ shadings,
where the shortest height should be
ordered to allow for full rotation
of the bottom rail.
Outside (OB) Mount
- Measure the desired width and
height. To minimize light leakage,
the shade should overlap the window
opening at least 2" on each side and
at
the bottom. Refer to the Mounting
Charts for recommended overlaps
for each product.
- When measuring the
height, take into account the
requirements for mounting the
bracket attachment. areas for over 8 years.
