Shade Cloth Deductions
As with all roller shades, the overall width of the shade, from bracket to bracket, is greater than the actual fabric width of shade. The fabric width of shade is narrower than bracket to bracket size of shade so that fabric does not roll up on brackets, and to allow room for mechanism and bracket within the dimensions in which shade is to be installed. For inside mounted roller shades, there is a small gap between edge of fabric and inside window walls. For roller shades mounted outside window frame, it is important to order shade wider than window opening to compensate for deduction made to cloth width, and to ensure total window coverage. See chart to right for the exact overall deduction made to cloth width for each roller type. See RollerView/Technical/Ordering instructions for more details.

Bottom-Up Spring Roller Mounting Brackets
Bottom-Up Spring roller mounting brackets are not universal, and not the same as standard spring roller brackets. Factory will provide the proper mounting brackets for each shade based on installation specification on order. Ceiling mount, Inside mount wall mount, reverse roll and regular roll spring roller shade each require unique brackets. See RollerView/Technical for more details on installation types and roll direction.

Cord Pulls
A standard Bell cord pull is attached at end of cord which is used to raise and lower shade. Cord pulls are available in a wide variety if colors. Factory will match bell pull color to shade fabric unless otherwise specified.
