Size & fit
Overall size measures the outside of the trim. Inside dimensions describe the clear center opening and are separate from the wall’s required rough opening. Check the louver or window drawing, frame overlap and surrounding clearances before ordering. The inside height is measured from the open bottom baseline to the inside crown. Dimensions follow the individual drawing; the model number does not state the overall width.

Installation & finishing
Installation
Dry-fit the trim against a clean, prepared mounting surface and check that it is centered and level. Use ADH100 adhesive on all bedding and butt joints, with the manufacturer’s specified nails or screws for the substrate. Adhesive and fasteners are sold separately. Follow the manufacturer’s installation instructions and coordinate flashing, joints and weatherproofing with the wall assembly. Keep any louver drainage paths and ventilation openings clear.
Finishing
Supplied primed white. Prepare the surface and finish joints and fastener holes before applying compatible finish paint according to the manufacturer’s coating instructions.

Common questions
Is a louver included?
No. This product is the decorative trim frame only. Louvers, windows and other inserts are separate products.
Which measurement should I use?
Overall size measures the outside of the trim. Inside dimensions describe the clear center opening and are separate from the wall’s required rough opening. Check the louver or window drawing, frame overlap and surrounding clearances before ordering. The inside height is measured from the open bottom baseline to the inside crown. Dimensions follow the individual drawing; the model number does not state the overall width.
Does this trim provide ventilation?
The trim has an open center but contains no louver blades or screen and has no standalone ventilation rating. Ventilation depends on the separate louver and wall assembly.
Does it have a bottom rail?
This half-round arch is open at the bottom; no bottom rail is included.
Is it ready to paint?
Supplied primed white. Prepare the surface and finish joints and fastener holes before applying compatible finish paint according to the manufacturer’s coating instructions.
Can I return it?
