Size & fit
The width and height in the model description identify the inside opening, not the outside of the trim. Match the oval shape as well as both opening dimensions. Use the drawing to check the full outside clearance, including all four keystones. The side view shows a 2½-inch maximum projection; the general manufacturer listing gives a different projection. The dimensions above follow the individual CAD drawing.

Installation & finishing
Installation
Dry-fit the piece on a clean, prepared surface and verify alignment and clearances. Use ADH100 adhesive on bedding and butt joints, with the manufacturer’s specified fasteners and support. Adhesive and fasteners are sold separately. For exterior installations, coordinate flashing and weatherproofing with the wall or window assembly. Decorative urethane trim does not carry structural loads.
Finishing
The product is supplied with white primer. Fill and finish joints and fastener holes as specified, then apply a compatible finish paint. Follow the manufacturer’s surface preparation and coating instructions for the application.
