Right side Casement Operator

Thanks for posting. My initial thought was that this is an older version of something like our 39-027E, which has a 9-1/2" straight arm. See the diagram below.

However, it looks to me like the base of the operator arm might have an offset, or a bend that raises upward. It may just be the age of the device, but please investigate. If it does have this bend, the 49-412 may be the better choice. Take a look and see if you think either of these options could work for you. If something seems off, please let me know by how much.

In either case, for a new crank handle you can use the 39-114L, sold separately.
