This single sash (or window) lift was placed at the bottom of the window and used to raise the window. Since this piece has the flashed copper treatment, it dates from 1900 to the 1920s. It is steel with a copper coating and a flashing of black lacquer. Because of the sporadic flashing, no two pieces are alike.
The lift measures 3 1/4 inches long and 1 7/8 inches vertically. The piece is inset into the wood so the face of the lift is somewhat flush with the surface of the window. That depth is 1/2 inch. The opening for the fingers measures 2 1/4 inches by 7/8 inches. To secure the lift, two screws or brads are placed in the holes (two) that are inside ends of the inset.
This sash lift is in very good condition. The flashing is intact and has not rubbed off. There are a few minute surface scratches.
