Series 5520

Thanks for reaching out to us! It looks like you're looking to replace the track for your casement window operator. Take a look at our 39-505 4 hole track and 39-533 3 hole track. Carefully look over their dimensions and design to confirm if either of these is the replacement you need.

The track is the metal piece installed to the bottom of the swinging window sash. That is the piece that the end of the operator arm slides into and helps to guide the straight arm on the operator when opening and closing the window. From what I see in the photo, that is the only part that seems to be completely rusted.

The part that goes into the operator track is the wheel that is riveted into the end of the operator arm. If this has also been rusted out, you'll need to replace the entire operator. Unfortunately, the wheel cannot be replaced.

Your operator reminds me of the 39-031 EntryGard Dual Arm Operator; the opposite handed version is the 39-032. Take a look over the dimensions and design to confirm that this is the correct replacement.

I've tagged a few of the compatible covers and handles below, as well.
