Casement window crank parts

Your operator appears similar in design to our 39-220B. Look it over and let me know if you had any questions. We also sell the 39-452 cover/handle set separately.

Your second photo shows the top hinge, so you presumably need those as well? If so, see our 36-048. As long as your base track is 10" and as long as you replace the top and bottom at the same time it should work fine despite any evident differences.
