(Optional: 3/32 drill bit may be needed for pre-drilling holes. This is used for mounting into wood that may have a chance of cracking. Pre-drilling holes may be desired for regular installs to help start pilot the screw.)

Mount brackets through valance into jamb or ceiling. Install track and vanes. Now you're ready to install the sheer.
OUTSIDE MOUNT
Mount brackets 1/2" higher then ordered blind length. Install track and vanes only. Now you're ready to install the sheer. Leave valance installation for final step.
