Cannot ID Any Names, Numbers, Markings, etc.





Good catch! I didn't notice at first because your operator spline where the handle installs broke off so evenly but since it does appear to be damaged, you will need to replace the entire assembly. It's hard to be sure of which operator you have based on seeing the arms through the screen, but it does resemble the 39-220B and 39-221B. Take a look and see how the specifications shown on our product pages compare to yours to confirm.

I assume I need a LH mount but can you confirm?
Also, if these parts you recommended are not the correct fit, what is your return policy?




We base handing for these types of operators based on the side of the base that the handle attaches to. If the handle attaches to the left side, you would need the 39-220B. If it mounts on the right, see the 39-221B.
Unfortunately, the 39-375 and 39-376 handle and cover kits used with these operators are not available in gray but we do offer multiple color options to choose from on our product pages.
If you run into any problems with your purchase, you are welcome to review our return policy here. Thank you!
