split arm operator

Hello! That code is frequently associated with our 39-220B and 39-221B operators. These may be what you need, but you should review each product to verify. Those codes aren't a guarantee and it's always better to triple check every detail before you buy anything.

Assuming these are a match, then you may also need a new 39-451 and 39-452 cover/handle set to go with them. The cover from the old operator may not be reusable, depending on how old it is.
