Hi there!
Thank you for reaching out to us. Can you write out the distance between the two installation holes, measured from center to center? We'd also like to know the backset, which is measured from the center of the installation hole to the top edge of the lock.
I can't promise we'll have a suitable match, but those details will help confirm.

Hello the distance from the installation holes is 2 1/4 in. And the backset is 7/16 in.

Thank you! Our 90-300 sash lock measures 2-1/4" on the installation hole centers with a 7/16" backset. Review the specifications and see what you think.
