The Decorative Arm M156 (DA-M156) is a premium architectural mounting arm engineered for durability, structural strength, and aesthetic appeal. Constructed from extruded aluminum tubing and cast aluminum (356 alloy), this decorative arm delivers long-lasting performance in commercial and municipal lighting applications.

Designed to mount over round poles or tenons ranging from 3” to 5” outside diameter (OD), the DA-M156 is secured using 3/8” stainless steel set screws for a stable and reliable installation. Multiple mounting configurations—including single, double 180°, and wall mount—provide flexibility for streetscapes, campuses, parks, and architectural lighting projects.

All Decorative Arms are proudly designed, fabricated, and assembled in the USA. Custom configurations and mounting solutions are available upon request.
