Casement window parts

We found that product code: 39-089 is similar to what we have. However, the the arm length is only about 4-1/2" instead of 5". Thank you.

I actually think this operator is closer to our 39-187. I know they look the same, but the key difference is the gear arm. The 39-089 has more of a "Z" shape, while the 39-187 and your own operator are more like a "W."

As for the smaller link arm, I'm afraid we've never been able to find a version of either that has it. The only things I can recommend is either moving the sash bracket 1/2" over to compensate, or to drill out the link arm from both the new and old operators, then to install the old link arm on the new 39-187 with a 62-014 rivet.

Thanks Dave. I think I will try to use the old link arm for the new operators. My question is how to detach the link arm for both the new and old operators. Thank you again.

You will need to drill out the link arms to swap them.
