Discontinued Allen Stevens locks and keepers

A landlord from Seymour, CT, USA says:
Looking for something compatible for several broken locks and keepers. Have the discontinued Allen Stevens part number. The locks have a rabbit in base to match window sash frame. Attached picture has measurements. Any suggestions appreciated.
Thank You

Hello,

As you mentioned, the Allen Stevens Corporation has been out of business since the late '90s, along with their hardware. With that being said, we've related our 90-161 lock with 2-1/16" hole spacing and the 90-257 keeper with 7/16" hole spacing. We can't make any guarantees but take a look and see if these parts could be adapted to work for your application. Thanks for posting!
