Width measurements need to be taken at the point where the roll shade installation brackets will be mounted. Measurements will not be accepted by the desired material width or height. Use a steel measuring tape. Enter measurements in inches and in fractions, round down to the nearest 1/8”. Measurements by the foot or metrics are not accepted.

(IM) measurements are for mounting the shade brackets within the window casement, the factory will make deductions to accommodate the brackets, shade, and rotating control mechanism. Inside mount (IM) shades will ALWAYS have a gap of up to 5/8” on both sides of the shade. < plus or minus 1/8” > EXAMPLE: a shade ordered at 70” IM width will fit within 70”. NOTE the material width including bottom bar will be approximately 68 ¾”. The “gap” is the spacing given to accommodate the brackets and mechanism that hold and control the shade. If this gap is not acceptable, consider adding inches to the shade and mount it on the wall, trim or mullion for an Outside Bracket Mount (OB) We do not accept material or bottom bar width when ordering. If there are any obstructions (trim, molding, handles) this must be taken into consideration to have a customized fit. Photographs and or additional measurements may be required. Material width or bottom bar width is never considered as a viable measurement in and of itself.

(OB) measurements are for mounting the shade brackets on the outer casing, on the ceiling, trim, molding or mullion. This measurement will be manufactured with NO factory deductions. When ordering OB measurements, you can customize the opening for no-light gap coverage by simply increasing the mounting width size. The final rule is; Measure to and from the point of the bracket installation. Material width or bottom bar width is never considered as a viable measurement in and of itself.

The minimum mounting depth for IM is 1” (brackets and shade will extend past the opening) For fully recessed shades the depth must be 3”. The tubes and mechanism become larger for shades that measure beyond 76” wide. The large shade will need a 4” minimum depth to be fully recessed The factory always adds length to each shade as a “safety wrap”. This insures that the material will hang securely to the tube. The material safety wrap remains around the tube when the shade reaches the ordered length.

The default length of the chain is 60% of the shade’s ordered height. A roll shade positioned over a door or a tall window where the windowsill is greater than 48” from the floor will need extended chain length. The extended chain will lower the drop length to allow reach and access to the roll shade. An extra chain must be requested at time of order.
