The Norton Door Closer 1601 has been around for the past 40 years.  With the advent of aluminum framed glass doors, Norton was on for the first manufactures to come up with a narrow stile door closer.  Because of this, it is still one of the most popular door closer model out there.  It is a Grade 1 closer and has adjustable closing, latching, and back check speeds.  The model we ship also has adjustable spring tension to work on a wider range of doors.  The hole spacing is 3/4” x 9-1/16”.

Older models may be stamped with Scoville or Eaton, which are the companies that used to own Norton.  We sometimes find 20-1624-4001, or 20-1604-4001 stamped on the back of the closer. If your door closer is stamped 20-1603-4001 or 20-1623-4001, you might want to double check the hole spacing. The 20-1603-4001 usually has a hole spacing of 3/4" x 8-3/16", you could use the International Door Closer 853 as a replacement.
