I was looking at the Ellipse Style Single Arm Operator, 9-1/2" Or 9-1/2" Single Arm Operator, SS Roller

Thanks for reaching out to us! There is a chance one of these operators could work for you, but you'll need to be sure to carefully compare the dimensions as they are shown on the diagram to confirm. You'll be able to get a more accurate measurement by disconnecting the arm track from the operator and comparing the dimensions.

The difference between the two operators mentioned is the wheel at the end of the arm. So you'll also need to confirm if yours is a metal wheel versus a nylon wheel.

Take a look over their dimensions and design to confirm. If these are not the operators you are referencing, I'll need to know the product codes rather than the names of the operators.
