Double Hung Window Sweep Locks

A home owner from New York says:
The sweep locks are white and are from windows that do not have any manufacturer identified that I can see. The only markings I can see are on the bottom of the lock piece which has a one on the embossed on the lock, a 9 (or 6?) on the sweep and an icon that looks like a triangle within a triangle also on the bottom of the sweep.

Thank you for contacting us. I would start by looking at the 90-161. Carefully compare the specs we show to your own hardware and see if you could use this as a replacement.
