The factory accepts as either Inside or Outside Mount only. The proper installation brackets and valance returns will be provided depending on the product ordered and the type of mount.
Inside measurements represent the exact window opening size from which deductions must be taken to fit the blind inside. Outside measurements represent the exact blind size needed. Using the word exact when ordering may create confusion between window measurements and blind measurements
Use a steel tape measurements. Never use a cloth tape as it may stretch.
Caution: J.C. Blinds are custom made to your measurements and are not returnable. The factory can not accept changes or cancellation after materials are cut.
1. Measure the width of opening at top, middle, and bottom, and use the smallest measurement when ordering.
2. Measure height of window opening on left, center, and right, using the smallest measurement for Verticals, and use the largest measurement for Horizontals.
3. The minimum recess space required for an inside mount is 2 1/2" for verticals and 1" for minis.
1. Measure the width and height of the window (figure 1). A 3" overlap on each end is customary, but you may specify any length greater or less than this.
2. If mounting brackets beyond the casing or on a door with molding you will need projection brackets or spacers. Spacers provide 1/4" each, and projection brackets are available in two sizes: 2 7/8" (small) or 4 7/8" (large).
For any window where the blinds are butting together (whether a bay window or a corner application), the best product choices are those that maintain the same depth when opened as when closed. Cell shades remain constant when in the raised or lowered position. Wood blinds don't. When the slats are open there is a depth of approximately 2 1/8" and when closed you are looking at 1" or less. This means if you position the blinds butting together with the slats open, you will have gaps when you close your blinds. It's always a good idea to contact the factory to find out how wide the headrail is on the blinds you want to use. Even though cell shades are probably one of the best prodcuts to use in bay windows, there will be a gap because the fabric is usually narrower than the top and bottom rails. As always, you can email me with help in this area.
