The One Systems PM4.M is a pole mount suspension system that permits a variety of One Systems loudspeaker models to be safely attached to light or utility poles. The PM4.M is designed to be used with the 112.HSB, 112.HTH, 118.HSB, 212.HC, 312.HC and CFA2.HTH models. The PM4.M is constructed of 316 marine-grade stainless steel and can be used for oceanfront and cruise ship environments as well as inland direct weather installations or general indoor applications. The PM4.M will accommodate installations of speakers on poles with diameters of 10 inches (254 mm) or larger (it is necessary to consult the pole’s manufacturer prior to installation to insure safe operating limits based on pole construction, local wind patterns and compliance with local and national codes). The PM4.M also includes a tilt function that allows down tilt up to a maximum of 35 degrees and is adjustable in 5-degree increments. The system attaches to the mounting pole using a stainless steel band and clamp system available from BAND-IT-IDEX Corporation (more details are included in the PM4.M's installation manual). Other hardware necessary for attaching the speaker to the bracket is included with the PM4.M. The PM4.M is available in black and white finishes to match the attached loudspeaker models.
