Newbie question on cowbell mounts

[GCRoberts]

I was looking at a LP Rock Ridge Rider Cowbell. The mount is welded on in a slight angle. Probably two thirds of LP's cowbells have the same angle, but the rest rest have a perfectly squared bracket on them. What is the reason for this angle?

I've got a pearl cowbell with that type of angle in the mount. I think it's designed that way to be more practical when you mount 2 cowbells on the same rod.
