Andersen® primed wood casement windows use an operator to open and close the window sash. The operator consists of a gear mechanism and an operator arm that extends and retracts to open and close the window.

To identify the replacement operator needed for your window, the vintage of your window is required. Depending on the vintage of your window, the replacement operator may not appear exactly the same as the operator being replaced.

1936 - 1952: Primed casement windows manufactured prior to 1952 did not have a glass etching (unless replaced). To determine your window vintage, compare your operator to the discontinued operators shown below for 1936 - 1960 primed wood casement windows and use the visible glass dimensions.

1952 - 1989: To determine your window vintage, locate the Andersen® Glass Logo etched into the corner of the glass. The glass code etchings were implemented in 1952.
