Crestline casement windows parts

Question

I'm needing some guidance on Crestline parts for my casement Windows. I'm assuming I require a whole new assembly (operator?), but want to insure I purchase the correct parts.

The longest arm has "Entryguard Truth" on it and the shorter arm has number 20810. I assume this is dual arm?

I am seeking new plastic coverings and crank handles as well (as depicted in photos).

Question: how do I distinguish right-handed from left handed operator mechanisms? Do I look externally into the house and see which side the operator mechanism is located?

Greatly appreciate the guidance on distinguishing left/right Operators, part numbers for crank handles and part numbers for plastic coverings.

Thanks

Hello! Every manufacturer defines "left" and "right" differently. It can be aggravating. Sometimes its from inside the house, sometimes its outside, or even what side of the window the part sits on.

Personally speaking, you'd be better served just looking at the physical details of the operator, like what direction the arm goes, where the gears are, etc. For example, looking at your photos, I can tell the the operator in your first photo is the 39-031 and the operator in your second photo is the 39-032.

At least, I'm pretty sure that's what you have, ignoring left and right for the moment; you should compare your dimensions to yours to confirm everything lines up. We have detailed photos and dimensions on each product's store page that you can use as a reference.
