Perfect Fit® DuoLight Mosaic Cool Grey

Measure the visible glass area of your window.

The frame depth of your window is the 'thickness' of your PVC frame, from the glass out to the front of the frame.

The brackets we send with your blind will need to protrude far enough from the glass to clear the frame, so we offer a range of bracket sizes to cover a variety of frame depths. Simply choose the option from the drop-down that matches your window's frame depth.

An easy way to check your frame depth is to place a credit card or store card over the corner of the frame, then measure out from the glass to the edge of the card.
