Searching for GU Casement hinge

Sure thing, Steve. We might not have an exact match for this hinge, but you still may be able to use our 36-048 as a replacement. This is a very common and very adaptable hinge that can work in many different kinds of windows. The trick is that you have to replace the top and bottom at the same time so that the window has symmetrical operation. That's why the 36-048 comes as a pair.
