5700 Series Operator Features Size 1-6 1601 Door Closer

The Norton 5700 Series low energy operator will use the 1601 size 1-6 adjustable door closer body, effective immediately. This update will allow one unit to cover spring sizes 1 through 6.

With this change, models 5711, 5731 and 5741 are discontinued.

The 5700 Series' proven, long-term reliability is further enhanced by key features of the 1601, including a heavy-duty, cast aluminum body and rigorous testing. This unit installs in minutes rather than hours and consists of three basic components: inverter, motor and the 1601 closer.

  • Push or pull side mounting
  • Non-handed
  • ANSI/BHMA A156.19 certified
  • UL / cUL listed for use on fire rated doors
  • ADA compliant

The 5700 Series is available for order now. Standard lead times apply.
