I'm replacing a Marvin casement sash that uses Truth hardware. Some of the original hinge got tossed out with the old busted sash. I have the components labeled 90941 (top) and 90942 (bottom) and the hinged arm that has the "Truth" brand on it (see photos), but I'm missing the components that attach to side and bottom of the window sash itself. Attached are 2 photos of what I have in place (top and bottom), plus 2 of another window with all the parts in place with the same orientation as the one I'm trying to fix (right side hinged). Thanks in advance for your guidance. Nathan

Hello,

Take a look at the 36047 hinge set. This is a versatile option that should work as long as the 10" long base matches yours. Thanks for posting!

Thank you, Casey. Mine are indeed 10", so those look like the right parts. A couple more questions. Does one "set" work for both right and left mounted windows? I assume you'd just switch the top and bottom hinges. Also, I realized that I need the hardware that locks the casement to the window frames. I've added a couple more photos of those parts from another window. N

Unfortunately, we do not carry the alignment parts shown in your first photo. The second photo is similar to the 38-089 keeper, which is commonly used with the 38-075 sash lock. Take a look and see how the specifications compare to yours.

As for the 36-048 hinge set, they can be used for left or right-opening sashes. You'll just need to install the new arms to match the orientation of the originals.
