Norton Rixson 252050L Floor Closer Arm Pack - Bottom Arm Package for 20, 27, 51 Series Floor Closers
Bring your center-hung opening back to smooth, controlled operation with the Norton Rixson 252050L. This left-hand arm pack is the factory replacement for Rixson 25 Series floor closers. It couples the door to the closer spindle, maintaining alignment at the bottom of the door so the closer can do its job—controlling sweep, latch, and backcheck while the door opens and closes quietly and predictably. Built to commercial standards, it’s ideal for offices, healthcare, education, and other high-traffic facilities where uptime matters.
