I know the addition to this house was built in 2006. I have several operators that need replacement but I can't seems to identify them. Hoping you have a suitable replacement. Thank you!

Hello there!

We can definitely help with this. The operator in your photo looks like an older version of the 39-315 and 39-316. Look over the specifications and compare them with yours to see how they match up.
