I'm afraid we've never been able to find a version of the 39-188 with this size arm. There are a couple solutions you can try, though both will require a little handy work.
The first is to adjust the bracket on the sash to which the old 4-1/2" long arm attached so that it will better work with the new 5" long arm. The second is to drill out both arms, then put the old 4-1/2" arm on the new operator using our 62-014 rivet. |
