See our 39-031 & 39-032 Operators, or our 39-155 & 39-156 types. These operators are very similar, with a slight difference in the link arm lengths beings the difference, so compare both sets with your old hardware to see if either matches what you need. For a new cover, see the 39-107. For a new handle, see the 39-114L, or if you wish to stick with the T style, see the 39-102.

Sorry... I didn't get any notification of a response, even in spam. I believe my question was whether the operator cover and the crank handle from SWISCO would be a match for the Crestline operator cover and crank handle I don't need the actual operator). Should I assume from what you are saying that they will fit without a problem? Just want to be sure. Thanks.

I wouldn't worry about the brand of your window. Your window may be Crestline, but your operator parts are made by a company called Truth. Truth operators and their related hardware are used by many, many different window manufacturers, Crestline included. For the purposes of this project, though, you can forget about the name Crestline entirely.

I should also make it clear that we don't manufacture parts, we're just a third party supplier. We happen to supply Truth parts, too, and the products that Bob recommended appear to match the parts you show in your photos. Ultimately, you need to compare the physical details (design, dimensions, etc.) of our products to your own hardware to confirm if they work. There are a lot of different Truth parts that are kinda similar with only slight differences, so if you want to be sure of what to get you have to do a little homework. We have detailed information for each product on their specific store page that you can use as a reference.
