FlexShades are custom fabricated for each opening, and must be measured accurately.

• Determine the area to be covered and decide where brackets or endcaps will be attached.
• Be careful to allow for any irregularity which will interfere with the proper operation of the unit (i.e. handles, irregular trim, locks or opening not square and plumb.)

IM: If mounting inside the opening, give the exact opening width at the head. Call this IM (inside measure). Draper will make necessary deductions. Measure head to sill for exact height. Draper will add the extra fabric for roller wrap.

OM: If mounting outside, give the overall width dimension desired, including all hardware. Call this OM (outside measure). Draper will make no deductions. Also give the exact height desired.

Cloth Measurement: Exact width of cloth. Depending on product, overall width may be wider than fabric.

Pocket: If mounting shade brackets or headbox in a pcoket above window opening, give the exact overall height (top of pocket to sill) and the exact width of pocket. Draper will make necessary deductions.

Seams: Shades that are both wider and taller than the maximum available fabric width in any given style will be seamed horizontally ("transversed" or railroaded") at Draper's discretion with the seam placed as high as possible from the bottom of the shade up (standard) unless otherwise specified.

Stays: Draper may, at our sole discretion, add stays in pockets or at seam locations to imporve surface flatness and reliable operation. Stays are made of spring steel and measure 1/4" wide and are inserted in pockets in the fabric measuring approximately 1 1/8" wide. Shades over 10' wide OR over 14'in height will have stays placed at intervals of no more than 96" (Colossal shades taller than the widest fabric width have stays at intervals of no more than 63").

Note for LightBloc and Skylight Systems:

IM LightBloc - Draper will deduct 1/8" from your exact opening dimensions in both width and length. Be sure several measurements are taken to discover any irregularities in the opening.

IM Skylight - Draper will deduct 3/4" from your exact opening dimensions in both width and length. Draper provides angles to be installed around the opening and the shade rests on the angles. Be sure several measurements are taken to discover any irregulartiies in the opening.

OM LightBLoc and Skylight - Draper will fabricate the unti to your exact dimensions, taking no deductions.

Note which unites, if any, abut at mullions.
