Hello All, Long time no chat,
As for end rails... very common in Australia at least, The idea is to use them to stop thin work from being ejected off the end, the belief being that thin work often has too little available mass and therefore the magnets don't necessarily grip so well, so you lift the rail up just enough to stop the part slipping off, we used as little as 0.25mm of height to help hold a 0.5mm shim, as I said just enough to assist the magnet, if the wheel does grab the part aggressively it will do so at the other end of the job as it is starting to cut in which case the shim can skip up over the rail and fly away but once the wheel is on top of the shim it's vertical force helps the magnet grip the shim.

Whatever it is, do it today, Tomorrow may not be an option and regret outlasts fatigue.
