Replacement patio door hardware

Cole Sewell has been out of business for a long time now, so there is a good chance you won't find the exact lockset you need. It's also very difficult to determine an alternative without seeing the original handle set itself; all I can really see in your photo is the door, which is not sufficient to make a confident recommendation.

A good product to look at starting out might be our 40-049. This works on similarly designed doors, but you will need to carefully review its design and measurements to confirm whether it will be compatible with your door. It is, ultimately, an educated guess.
