Place the casement sash interior side up with the bottom of the sash closest to you. You will see dashes and circles around the perimeter of the sash, showing spots to pre-drill for your hardware.

Attach the sash bracket. At the bottom of your sash, find the dash nearest the edge, and drill a spot for your sash bracket, this will be on the hinged side of your sash. Then, using the sash bracket as a template, drill the rest of the holes, and secure your sash bracket with screws.

Attach your hinges to the sash. Using the hinge with the dark-colored shoe on the bottom, position the first screw hole over the dash just beneath where you attached the sash bracket. Using the hinge as a template, drill out the rest of the holes for the hinge's screws. Repeat the process using the hinge with the light-colored shoe.

Attach the lock keeper(s) to the side of your sash opposite of the hinges. There will be 1 to 3 based on the height of your casement window. Pre-drill holes at the dashes for them, and secure them with screws.

Lift your sash into the frame of your window. Attach the upper hinge and then the lower hinge onto the frame. Continue to support the sash within the frame until your operator (crank) is attached to the window sash.

Screw the operator base onto the sill of your casement window, and place the wooden trim piece (known as a sill stop) over the operator cover and crank. Attach the end of the operator's arm to the sash bracket with the clip, making sure it is secure.

Tips & Warnings
Do not mistake a side-opening casement window for an awning or hopper-style window that crank out from the top or bottom, respectively. This job is best done with two people. One person to hold the window sash, one to remove the old hardware and attach the new hardware.
Only drill 1/8" into the sash with a 3/32" drill bit so you don't break the glass.
