help identify screen door roller

This is a relatively common question, but it's a little tricky to answer. The main difference between the 84-096 and 84-108 is how they attach to their respective corners; it's a little hard to describe, but the 95-248 has a solid bar in its back bottom corner that hooks onto the 95-248 corner. The 84-096, meanwhile, has an empty back bottom corner that pinches close over the 95-227 corner.

Hopefully that makes sense. Let me know if that helps clarify which roller would work best for you.
