Double latch mortise patio sliding door lock and keeper

Hello there!

Thank you for reaching out to us. The mortise lock shown here looks like the 82-239 or 82-265 depending on the faceplate yours uses. The keeper looks like the 82-249. Review the specifications for these parts and see how they compare with your old hardware.
