Hi - I need to replace the window locks throughout my house. Here is a photo of current lock and measurements, can you make a recommendation on what to buy. I'd like something in white.

Hello,

We'd be happy to look into this for you but it's tough to make out accurate dimensions from photos. We would need you to write out the exact dimensions of your lock, including the distance between the installation hole centers, to compare to our inventory. Thank you!

Thanks for getting back to us. Unfortunately, we do not carry a sash lock like yours with 2" hole spacing but we do offer the 90-077A with 2-1/16" installation holes. This lock is used with the 90-177 keeper. Review the specifications below and see if these replacements could work for your repair.

Thanks, these worked! Do you not provide the screws to install the locks?

Unfortunately, the lock does not come with fasteners since the correct replacements depend on what was used to install the lock originally. We generally recommend reusing the original screws or bringing one of them to a local hardware store so that they can match you up with the correct replacements.
