I require a replacement part for my window crank circa 1954. I have attached a picture for your convenience. If you have available please provide cost and part number. Would I have to buy in a pair ie left and right side ?
Replacement part




Hey there, thanks for posting! If you are looking to replace your casement operators, I believe our 39-090 and its opposite 39-089 are a great place to start. Take a look at the dimensions to confirm that this is the right fit. Also, pay special attention to the other details of the operator. If they are not a match, let me know.
I've included the dimensions for part 39-090 below. These operators are compatible with the 39-114L crank handle.

There is a chance that you may need to replace the hinge as well. If so, a good place to start would be our 36-048. Keep in mind, you'll need to replace top and bottom at the same time to ensure that the hinges will match; to maintain the integrity of the window function. These can be used for both the left and right side of the window. Take a look and see what you think.
