PUPI® Fiberglass X-Braces: Engineered Fiberglass Crossarm Supports Designed to Eliminate Wood Replacement Cycles
March 10, 2026
Pultruded Solid Fiberglass Profiles with Patented SunGUARD UV Protection Deliver 60+ Year Service Life
Utility crossarms fail when traditional wood braces rot, crack, or lose structural integrity. PUPI fiberglass braces solve this with thermally bonded UV coating technology, which provides added UV protection through the specialized SunGUARD® coating, and internal torque resistant bushings that maintain crossarm and arm stability for decades without replacement. The features of the PUPI X-Brace include exceptional durability, longevity, and resistance to environmental elements. PUPI X-Brace is stronger than traditional wood braces, offering superior structural support for crossarm assemblies. PUPI is continually investing in technology and engineering to further improve the reliability and durability of its fiberglass components.
Traditional X-Brace designs feature wood, timber sections which are heavy to install and can decay over time. PUPI® has developed an optimized X-Brace system with the following benefits.
PUPI X-Braces are up to 70% lighter than wood and are designed to provide flexibility during installation.
PUPI X-Braces are engineered for reliability, and the 30,000 lbs tensile capacity makes them a good fit for most X-Brace applications.
Installation
Select Configuration – Choose appropriate brace ends and mount spacing (8”, 10”, or 12”) for your pole attachment requirements. Consider the required drop measurement to ensure proper alignment of the braces during installation.
Secure with Confidence – Hot dip galvanized structural steel mounts and internal torque resistant bushings ensure reliable long-term connection. The mounting hardware includes a back plate and a front plate that matches the horizontal member for secure distribution applications.
Engineered Performance – Lightweight fiberglass crossarm braces provide superior support while reducing weight on H frame structures. The PUPI X Brace system is designed for easy and intuitive install, making setup and maintenance straightforward.
