Fiberglass Brackets: Enhanced Veiled UV protection system

MacLean Power Systems has made improvements that affect fiberglass brackets. Fiberglass bracket's primary function is to provide mechanical support for mounting equipment and insulators to electrical systems. They can be used to support everything from arresters, cutouts, and terminations to insulators with conductors, as an added benefit of using MPS fiberglass brackets. Electrical separation from the pole to the guy wire for safety and system reliability. Maclean's full line offering of fiberglass brackets provides complete solutions for all environments and applications and is available in multiple lengths, strength ratings, and our veiled UV protective coating. Every fiberglass bracket assembled in the USA is 100% factory tested for proven reliability out of the box.

Advanced Coatings

The silicone coating offers improved UV protection and contamination performance characteristics. MPS's extruded HTV (high temperature vulcanized) silicone rubber formulation has been lab-tested and field-proven since 1984, is completely bonded to the fiberglass rod during production, won't tear away or fall off over time, eliminates potential voids to prevent moisture ingress, and provides the same insulating protection and hydrophobicity performance as MPS's high voltage transmission insulators. All MPS fiberglass brackets come standard in MPS enhanced UVMAXX ™ veil coating system(Fiberglass Bracket Veiled UV Coating).


  • Anticipated to last 80+ years
  • UV Protective top layer integrated into structure of composite eliminated concerns of protective layer chipping or scratching off 
  • Double thickness of top layer
  • Denser fabric for reduced light transference and prolonged lifespan
  • 10,000 hours of UV exposure, testing per ASTM G154
  • UL 94 V0 fire rating
  • Improved tracking and erosion resistance
