replacent casement window hardware

Hi Ed,

Thanks for reaching out to us! The operator you have here more closely resembles the 39-253RB Encore Dual Arm Operator which uses the 39-529 Truth Hardware Track Slider. Take a look at the video below that details the differences between the operators for an in-depth explanation. Be sure to look over the dimensions to confirm that this is the replacement you'll need.

I've tagged the other compatible hardware components below this thread.
