The Corbin Russwin Lever Trim Passage Function N610 626 is an exit trim that is meant to be used with the ED8000 series of panic bars. It is installed on the outside of the door that the panic hardware is on and allows people to come in through the door. This is a passage function lever which means that turning the handle will activate the latch if the door is not locked. This lever trim does not have a lock itself.
