Looking for both left and right window sash lock
Your tilt latch reminds me of the left handed latch from the 26-408 Tilt Latch Pair. To confirm that this is the correct replacement, carefully review and compare the dimensions below.
I'd also like to note that the part in the window track, right above the latch, is the 15-087 Coil Housing Pivot. This part should not be positioned where it is in the window track. It is part of the coil assembly that helps to support the sash weight, when opening and closing the window.
The pivot bar, installed on the bottom of the sash, is no longer connected to the blue cam in that shoe. This means the window may no longer stay up when open.
Be sure to double check that the balances and/or the pivot bar do not need to be replaced as well.
