Installation Instructions
Bay & Bow Windows
Permanent Support of Window
- Install the cable cleats supplied to a structural component of the framingusing the screws provided. Two examples of possible locations are shown in the illustration to the right. Be sure to position the cleat so the cable will have at least a 15º angle when installed.
- Attach the cable-turnbuckle assembly to the brackets on the top of the unit. Be sure the turnbuckles are adjusted to their longest length at this point. Wrap the other end of the cable around the cleat from bottom to top in a criss-cross pattern from bottom to top and back down, making it as tight as possible.
- Slowly lower the jack supporting the outside edge of the window until the weight of the window is supported by the cables. Double-check the security of the cable and cleats. Using a level on the seatboard, tighten the turnbuckles until the window is level from front to back. It may be easier to adjust the turnbuckles by raising and lowering the window with the jack. Be sure to tighten both turnbuckles evenly.
- Once the unit is level in the opening, fasten the head, seat, and side boards to the rough opening from the interior with 10d ss finish nails or 3” trim head screws spaced every 12” to 16”. Shim behind the fasteners if necessary. NOTE: if the cable support system proves unworkable for your installation, other means of support may be employed such as knee braces (shown), posts, etc.
Finish-up and Adjustment
Complete the framing/siding and/or roofing details as per your specific requirements. Check the operation of the windows (if applicable) and make final adjustments as necessary. Install fiberglass batt insulation loosely in any interior gaps between the window and the rough opening. Install interior trim along the perimeter of the window frame.
