Crank casing covers

Question

5 3/8" at back and 3/4" in height.  Maritime Door and Window do not carry covers anymore as these windows are over 20 years old and want to replace cranks.  All windows are in excellent condition and closures working as they should.  Trying to find the plastic replacement covers as they are deteriorating.  Thank you.

I'm not sure if we have this exact cover. Our 39-107 comes to mind, but there's a good chance this is going to be too small.

The problem is that you have a somewhat older style of operator. They no longer make these with removable covers; they all come with covers built into the mechanism that are not made to be removed or repaired. As a trade off, they're also more resilient and less likely to break.

Because of this, there's no guarantee that our 39-107 will work. If it is too small then your only option would be to replace the complete operator mechanism.
