The roller is for our screen door in which we need 4. The other pictures are of the handles of the slider door as well as the locking mechanism. There are no markings/numbers on any of the parts.

Hello there!
Your hardware looks like it could be a good match for our 82-227 lock, 84-086 roller pair and 82-030 handle set with 3-15/16" hole center spacing. Look over the specifications for these parts and compare them with yours to see if they match what you need.
