Casement window hardware

Hello, thank you for posting,

Please start by reviewing the 39-253LB and 39-253RB or the 39-438B and 39-439B operators. The main difference is the guide at the end of the straight arm that engages with the sill track.  

Compare the overall dimensions and the video below for more details. Take a look at the product page of the correct operator for all related hardware that may be needed.

If you are also in need of new hinges, please start by reviewing the 36-048 2-bar hinge set that has a 10" sill track. Let us know if you have any additional questions!
