One tough PUPI.

Why PUPI® // Reliability

Trust in electrical structures is paramount in giving customers the piece of mind knowing structures are made to hold.

PUPI® crossarms are engineered products, manufactured with a fiberglass pultrusion process that creates products of the highest quality and consistency. Unlike wood, PUPI® crossarms are totally free from knots and imperfections that can cause failure over time. PUPI® crossarms can withstand transient loads that cause wood crossarms to fail. Because they are specifically designed for utility use, they have the strength to handle any situation, yet are also lightweight and easy to install.
