Atrium Window Cranks

A home owner from Walnut Creek, CA says:
I have seven broken Atrium window cranks: 4 right handled and 3 left handled. Please see the attached picture "AtriumWindowCrank.jpg". The number on the crank is 40425 and the operating arm is 9.4" long. Also, I have to replace the handle and/or mechanism for another Atrium Window shown in the attached picture labeled "AtriumWindow.jpg'>
Thanks for your help.

Thanks for posting! Let's start with the operator in the second picture first, since this is easier. The handle itself cannot be replaced; you will need an all new operator. See our 39-069 and 39-070 to start out. Based on the size you need, I am confident one of these will work. Unfortunately, we do not have it in gold.

The first operator is a little tougher. These aren't made anymore. You will need to substitute it with something like our 39-027E. You might need to change when back set when installing the operator base to the window sill. If you are not to handy, I would recommend getting the help of a local professional. Adapting the sill can be a project.
