'N Pattern' frames
Our 'N Pattern' lever frame closely resembles the NSWGR frame, with the levers laying back in the frame.
They are built in multiples of 4 levers, and employ what is known as "cam and tappet" locking, this is where the lever has a stud which traverses a slot in a cam which moves the tappet attached to it.
These frames can also be conditionally interlocked.
These frames have a discriptive number plate on the levers.
