The PM is engineered without compromise in the spirit of a large contemporary commercial bollard. Precisely milled from 6061 T-6 alloy, this model looks and performs like no other. Computer-designed parabolic reflector, diffuser cone and optics work together to produce long projection beam spread with no glare. All exterior components are finished with a military marine-grade process of acid etching, chromate plating and polyester powder coating to assure long-term appearance and integrity.
