Casement window operator

Question

I need to source two replacement casement window operators. Left and right side.

I couldn't determine the window brand and the only markings I saw on the device were the letters GU.

Hello, thank you for posting,

Your window uses an older GU operator that is no longer made. We recommend converting to the 39-315 and 39-316 operators. Please review the step by step video below that details the conversion and additional parts needed.

Let us know what you think and if you have any additional questions.
