Good afternoon - I have Farley Double Hung windows which have the left and right tilt window latches - are your ( tilt window latches ) compatible with the Farley windows - I purchased windows through Home Depot in 2001. Please let me know as the windows are now not safe..

Our records show various different latches used on Farley windows. Could you send us photos so we can help find you the correct latch? Thanks!
