82-101 or 82-102? Which do I need?

A contractor from IL says:
Between 82-102 and 82-101, how do I determine which one i need, also how do attach it to the frame as i currently don't have hardware for it.

Thanks for posting! You would want our 82-102 when you don't have a key lock and you'd want our 82-101 for when you do.
