Dimensions for 39-032

The compatible cover is part 39-107 and there are two compatible crank handles. There is a standard crank part 39-114L and a folding handle part 39-205. You also have the option of purchasing an entire folding handle kit which is part 39-107FK.

Take a look over these parts and review them to determine if they are the right fit for you.

 Any of the recommended handles will work as they're all compatible with the 39-032. It would be up to your discretion which one you'd like to install on your window. 

If you'd like to stick with a standard crank handle, the 39-114L would work perfectly. However, if you would like to switch over to a folding handle, other options are available as well.
