Sash Dyad Crank with a 3.5" arm

Hello,

Our 39-090 operator resembles what you show here, but we don't sell a version of it with a 3.5" link arm. If you're handy, you may be able to attach the original link arm to the new operator. You'll need the 62-014B rivet to do so. What you want to do is place the elbow of the link arm on a metal plate and hammer the 62-014B rivet until the skinny end mushrooms out and locks it in place. Take a look and see what you think.

Dimensions for 39-090

You would need to drill out the original rivet to swap the arms. Just keep in mind that modified parts can't be returned. 

We're happy to help and appreciate your business!
