The Legends Series DR300 is one of Trimline’s double-hung replacement wood windows. The DR300 offers residential and commercial remodeling solutions where full-frame window replacement is required. In addition, the DR300 also works for sash pocket installations. Sash pocket installation can only be used if an extruded aluminum panning system can cover the old window casing.
Another window option is the Liberty Series double-hung. Specifically, the L200 is an all-wood replacement window manufactured for a pocket insert installation. This installation method does not require the removal of the existing window frame, and the pocket sash sits within the old window frame.
