Casement lock, white 1-left and 1-right

Thanks for contacting us. If possible, can you show us a picture of the entire part? Much of the lock is obscured in your pictures. We will need to see the whole thing. That would be a huge help! Please also provide your measurements.

Thank you. Please see our 38-091 and 38-092 and compare the dimensions of the lock arms to yours. They might match but it will depend on your measurements.
