Hello there. This looks like a straight arm operator, such as the 39-013 and 39-014 13-1/2" Straight Arm, or the 39-027E and 39-028E 9-1/2" Straight Arm. Compare both with your old operators to see what matches best. These operators tend to use tracks like the 39-505 or 39-533. Compare both to see if either match what you need. |
