MASR Steel, Adjustable Pattern, Round Neck

Square/ Round Diffusers

This round neck diffuser’s removable core makes installation and maintenance easier and has no visible mounting screws since it uses a snap-in mechanism. It ensures a tight ceiling pattern with a horizontal lip on the louvers which allows excellent mixing.

  • Round inlet provided as a steel, factory-mounted square to round transition (SRM)
  • Snap-in center cores can be detached and interchanged between the same size margins
  • Available in standard White (WH) electrocoat finish that protects the diffuser from rust and other chemical reactions
