These latches are attached to vinyl windows. The locking mechanism is attached by two screws 2 5/8 inches apart. The locking receiver is held by two screws 1 inch apart. The only marking on the lock states "interlock".
The latching mechanism appears to be plastic set in some type of cast metal. The decorative/actionable cover plate is plastic. The activation mechanism has two plastic pins that insert into the plastic action of the base.

Hello, thank you for posting,
Please start by reviewing the style and dimensions of the 90-252 latch mechanism along with the 90-253 cover to see how they compare to your original. Let us know what you think and if you have any additional questions.
