Changing Arm and Including Foldable Handle

Question

Hi,

I am looking to see if 39-458 would be the best choice for this (pictured) for a single arm length at 13 inches (measured between the gear and arm to the end of the arm). I see the arm length is at 11 3/4. Does the arm length have an effect on the window?

It is a roller end.

I am looking to run a foldable white handle also with this.

Thanks.

Hello,

Your photos look like a closer match to the 39-013 and 39-014 operators to my eye, which are compatible with the 39-205 folding handle. One difference is that ours has a 13-1/2" arm, which could still work for you. You may need to move the position of the operator track attached to the window sash to compensate for the length difference, but not necessarily. Take a look and compare the specifications listed on our product pages to your assembly. Thank you!
