Pgt window gear box

Hello,

I would recommend starting by comparing the specifications of the 39-060 and 39-061 to your awning operator. If you notice any discrepancies, please write out your exact dimensions and we can go from there. Also, please note the position of the two bottom installation holes, which are tough to make out in your photos. Thank you!
