Patio Door Latch

Hello,

Unfortunately, we do not carry an exact match for your handle set. We may be able to provide something that could be adapted to work as a replacement but we would need you to confirm how your assembly engages with the door frame when locked. It's tough to tell if your door uses a type of internal lock or if the latch extends from the deadbolt itself. Thank you! 

Thanks for getting back to us. It looks like the part you are showing may be a deadbolt but I'm still not sure where the deadbolt is installed. Did it come from the base of the surface-mounted handle itself or from an internal lock inside the door? It would also help to see a photo of how the primary door engages with the frame of the other door that you mentioned.
