Crank and handle mechanism

Hey there. This looks like an Andersen operator. We need to see the entire mechanism, including the arm(s) that move the window. A bird's eye view, either with the operator removed from the window or at least with the window open, will suffice. We'll do our best to help from there. 

Thanks! Your operator appears to be a match for either our 39-094 or 39-150, depending on arm size. Review both parts to confirm the better option.

It looks like the arm might be longer than 9", in which case you'd need the 39-094 (its opposite-handed version is the 39-095). The 39-150 and 39-151 arm is shorter. But photos of measuring tape are hard to read. Do your best to measure and confirm which set is actually what you have.

In that case the 39-094 and 39-095 are our best possible matches for your old Andersen hardware. If you give them a try and they prove not to work, see our Return Policy here.
