If the window frame or handle protrudes and affects the installation, you can use extension brackets to provide extra depth for smooth installation.

Extension brackets are not available for inside mounts.

Valance and Fabric Size Discrepancy

Please note that the shade's valance and fabric are not perfectly aligned. The fabric on the motor side will recede by about 9/16 inches, and the fabric on the non-motor side will recede by about 3/8 inches. Therefore, if you require precise coverage, please take this discrepancy into account.
