Crank for casement

Hello! This looks similar in design to our 39-172, however I'm not sure about the size of your link arm. Your diagram shows it as 5-1/4", but in your post you say that the arm is only 3-1/2". Can you confirm? The arm on the 39-172 is 5" and I'm afraid that might be too big.

Yes, the link arm in question is the one in your photo marked with "B." To determine how to measure its length, refer to the image below of the 39-172 that I mentioned. The link arm length is indicated here at 5".

That's a relief! That fact alone saves you a whole lot of extra steps that we would have had to taken otherwise. 

At the end of the day, I think our 39-172 is definitely your best bet. 

Ah, I see. I'm afraid we don't have anything in that size. 1/4" difference may not be a big deal. There's a chance our operator will work as-is. If it doesn't, you could try adjusting the position of the mounting bracket to make up the difference.

Should even that fail, then there is a third option you can try. It involves using the old link arm on the new operator, which requires some drilling and hammering. We can cross that bridge when we get there, but it's always a good last-ditch solution. I'm hoping that we won't get to that point and that our operator will work as-is.

All orders for any of our products can be placed directly on our site. All you have to do is visit the product page for the part in question, click "Add to Cart," and then click "Checkout" in the upper right hand corner of the page to finalize the process.

That depends on what's broken. If your operator is broken, then replacing the handle won't do anything. Looking at your photos above, your handle still seems to be in good condition.

It's honestly very, very rare that an operator handle breaks before the operator itself. In addition to that, the handle doesn't really have any effect on the gears in the operator and how they function; all a handle does is make an operator spline easier to rotate. The operator is what's doing all the work.

Hey, Elise. I'm afraid I'm not familiar with your area. We're only in New Jersey so I'm not sure who youc ould contact in California. Sorry we can't help on that front!
