TrimLine - Clad Wood DH Windows
The TrimLine DR200 is constructed with a 3 ¼" jamb for a retrofit installation into the sash pocket of existing wood window frames. Virtually identical to a vinyl window installation, the DR200 is truly a replacement window.

The TrimLine DR300 is made with a 4 9/16" jamb for replacement applications requiring complete tear-outs down to a frame or masonary opening. With a snap-in nailing fin, the DR300 is ready for new construction.

Both the DR200 and DR300 can be furnished with factory applied extension jambs making it the ideal choice of window for either replacement/remodeling or new construction.
