Casement window bottom hinge bracket
Thanks for reaching out to us! The piece you are looking to replace is the track slider on the casement window hinge. Unfortunately, this piece is not sold separately from the hinge assemblies, at least not to our knowledge.
We can provide you with a replacement recommendation for the entire hinge assembly. I'll just need to know the measurement for the length of the track installed to the window sill.
In the second photo, I notice you are showing the length of the window operator arm. Were you looking to replace this hardware as well?
Thanks for confirming. The closest replacement match we have is the 36-048 2-Bar Hinge Set. Carefully look over the dimensions below and compare them to determine if this is the right replacement.
It is strongly encouraged to replace both the top and bottom hinges at the same time, to ensure they'll be a match. This set can be used for left and right handed applications.
