Hello, thank you for posting! This looks like either our 39-253LB & 39-253RB, or the 39-438B & 39-439B Operators. Review the dimensions to see how they compare to your original. The only difference between these two sets of operators is the guide at the end of the link arm. Please review the video below to compare the correct option. |
