he stopped slots on the outfeed table stop the travel of the sled before it can pass through the blade cover (and then my hand). This is by far my favorite feature and one I highly recommend. 

Really like the sled.   The safety features are well planned and executed.    Great work and design.

My outfeed table miter slots were to long to stop the sled before the blade came through the back      Cut a small slat, dropped it into the miter slot.   Now it the sled stops at the right point.    

Your sled looks a lot better than mine.   Nice.
