I'm not sure what you mean by "catch." Like, lock in to 50s and boardslides and stuff? And so you're saying to make them touching, right?
edit: Just for clarification, if you were looking down the rail, the rail where they would be touching would look like this: OO
and the rail with the gap between would look something like this: O-O looking directly down it.
