Windsor Casement Window Part
Yes, the part you are searching for is called the casement window hinge. To replace it, I suggest taking a look a the 36-048 and 36-004-10 (stainless steel) 2-Bar Hinge Sets. To determine which of these is the best option for your window, carefully review and compare the specifications below.
You will need to use one set to repair both the top and bottom hinges, for one side of the window. This will ensure they'll be a match. Both sets can be used in right and left handed applications.
