Norton 1601 Grade 1 Adjustable Surface Door Closer

The Norton Rixson 1601 is part of the 1600 Series of surface-mounted door closers, designed for moderate-traffic commercial interior or exterior doors. It features a cast aluminum body, a 1-3/8" diameter piston, NorGlide® fluid and staked adjustment valves.

The closer provides separate and independent adjustments for latch speed, sweep speed and backcheck intensity. Its non-handed design allows it to be used on left-hand or right-hand doors.

The 1601 is tri-packed for regular-arm, top-jamb or parallel-arm installation. According to Norton Rixson, standard arm applications permit the door to swing up to 180 degrees when opening conditions allow.

The 1600 Series is certified to ANSI/BHMA A156.4 Grade 1 and is listed by the manufacturer for doors weighing up to 250 pounds. The series carries a 30-year limited manufacturer’s warranty.
