Roller 84-010 - Is there a screw hole on top?

A quick learner from North Carolina says:
Is 84-010 replace the one shown in picture? It seems to be the same except I don't see a screw hole on top of white plastic part of roller assembly to attach to bracket

Great question. Our 84-010 does have a screw on top. It's located on the nylon housing. Please get back to us if any other questions about this product come up.
