For Casement and Sash Set Fixed Lite frames. Provides a good surface for returning drywall to meet the jamb.
Special Applications
• Step Jamb for Casement & Sash Set Fixed Lites The standard casement jamb surround is located toward the inner perimeter of the frame. A Step Jamb moves this to the outer most edge of the wood frame. This is valuable when mulling a casement family product to a non-casement family product, such as a direct set fixed lite or a double hung. This alternate jamb placement provides for improved trim alignment in these applications.
