Measure exact distance to the nearest 1/8" between inside surfaces of window frame at the top, middle, and bottom, and use the narrowest width. Do not make any width deductions. For custom blinds, the factory will automatically make appropriate deductions; for Trim+Go blinds, a 1/2" deduction will be taken on the entire blind.
Measure exact distance to the nearest 1/8" from inside surface at top of window to sill at the left, middle and right and use the longest height. If you prefer blind not to touch sill, deduct 1/4". If there is no sill, measure height to the point where the shade reaches.
Measure exact distance to the nearest 1/8" between the outermost points where the blind is to be placed. For optimal light control, this measurement should extend 3/4" beyond the window opening on each side (or 1 1/2" for the entire width).
Measure exact distance to the nearest 1/8" from where top of the blind will be located to the top of sill. If there is no sill or if blind is to overlap window frame, measure to the point the shade reaches.
|Allow Some Overlap|
|For outside mount applications allow the blind to overlap 1 1/2" to 3" on the sides, top and bottom of the window.
You must add the overlap to your measurement; LEVOLOR does not add width or height for overlap on Outside Mounted blinds.
Measure overall width of the area to be covered.
Measure width of the area each blind is to cover. Measure and specify the left shade first, continuing to the right. Factory will allow a minimum of 1/2" between blinds for operating clearance.
The total width of all blinds must equal the total headrail width. If ordering a valance wider than the blind, a diagram is required.
To measure height, use standard inside or outside measuring procedures.
There are different types of mounting brackets, depending on the headrail size and style. However, all types shown below work in a similar manner.
Style 3 (Inside Mount Only)
If your blinds include optional extension brackets, temporarily assemble them to the mounting brackets at this time. You will need to use the extension brackets to determine mounting hole locations in Steps 3 and 4.
Refer to the included instructions for your style of extension brackets.
To properly engage the headrail on inside mount installations, some bracket styles require up to 1/4″ between the headrail locking tabs and the mounting surface. If needed, use the included shims to ensure the necessary spacing.
If mounting into drywall or plaster, use 3/16" drill bit and insert wall anchors before inserting screws. Use two screws per bracket
Example: Installation in a wood window frame using the included screws. Use two screws per bracket.
