Window hinge/operator for Allwood Casement window
Thanks for reaching out! The metal part on the casement window that helps to pivot the sash open and closed is the window hinge. To replace your existing hinges, I believe you can use the 36-048, although, it may not be an exact replacement match.
Take a look over the dimensions and compare them to your existing hinge, see if it might be a fit. This hinge set can be used for the left and right side of the sash and you'll need to replace both the top and bottom hinge.
Keep in mind, you'll likely need to drill new holes to install this hinge.
