The Norton / Yale Door Closer 7701-3 Hold Open Arm is the standard hold open arm shipped with Norton and Yale Door Closers. It is known as a Friction Hold Open, because as the arm rotates it tightens down two plates together. Adjusting the large hex bolt on the Hold Open Assembly determines where the arm will hold open. This part has had a couple of numbers over the years 7701-3, 1620-3 for Norton and 400-3 for Yale.
