Thank you
Thanks for writing in! Your Pella casement window operator looks a lot like our 39-176 and its opposite handed version, part 39-175. To determine that this is the correct replacement, carefully look over the dimensions and compare them to your existing casement operator.
The compatible handle for this operator is part 39-109B.
We have several different window hinges however, it is hard to narrow down the options using your existing photos. If you are looking to replace them, you'll need to remove your existing hinges and compare them to the dimensions from our existing hinges.
Take a look at parts 39-351 & 39-352, 39-394 & 39-395, or 39-396 & 39-397 to determine if either of these might be the replacement you'll need. You'll find the dimensions for each of these on their respective product pages. Each of these pairs of part numbers is the left and right handed version for the hinges.
