Haven't got that juicy ILS auto-stacking upgrade yet? Want to slam 4 1800/min belts into one 7200/min belt? Haven't got a lot of width to put it in?
Give this a try! Comes with a right- and left-facing versions so you don't have to do any tricky copy-n-paste operations to change the direction of input. Just plunk this down out of the way and then copy out the one you need.
