This casement window opener is Marked "Roto" and has the stamp "HG05" with "2009U" below that. The length of the longest arm is approximately 9 10/16 in. Thanks for your help.

Hi Eric,
Your ROTO window operator reminds me of the 39-342 Roto Dual Arm Casement Window Operator. To determine if this is the right replacement be sure to look over them and compare them.
Be sure to take a look at the other compatible hardware and accessories tagged below to determine if they might need to be a replaced as well.
