This one is different! Unlike any other sash lift we have, this one is light weight, stamped steel, and has the flashed copper finish. Because of this finish, we can date this lift to 1900 through 1920.
The width of the lift is 1 3/4 inches. Vertically, each point is one inch. The mounting holes are 1 1/4 inches apart. The finger lift projects 3/4 inch from the surface.
Small round-headed black screws will be included.
