AtlasIED L20-220 APF Series Round Mounting Ring

The L20-220 is the round mounting ring and baffle for AtlasIED's APF Series compression driver horn, a double re-entrant design built for intelligible paging over a 15-watt driver. The ring supports both flange and recess mounting, so it fits flush against a wall or ceiling surface or sets back into an opening depending on the install.

Because the APF line ships in 25V, 70.7V and 100V transformer-equipped versions, the same ring covers whichever line-voltage horn the job specifies. It is built from vandal-resistant metal, which is the reason this family shows up in stairwells, parking structures and other outdoor or high-traffic paging zones.
