Thanks for reaching out! The window hinge you have here is a 4-Bar Hinge Set. Since it appears your sill track length is 10", you likely use either the 36-021 or the 36-021HD to replace it. These are "non-handed", so they can be used for either right or left hand applications.

To determine which of these is the best fit, you'll need to carefully look over their dimensions and design.

Can you please explain how they are interchangeable left or right hand application?

Sure! The "active arm", which is the arm installed to the bottom of the swinging window sash, can be rotated down so that the hinge can work for either a right side or left side installation.

When you rotate the "active arm", the others should follow.

I hope this helps!
