Underbuild

Maximize the effectiveness of your lines.

It’s common practice for Utilities to include distribution lines on their transmission poles. Fiberglass underbuild crossarms provide a reliable and maintenance free solution, which is also lightweight and easy to install.

 

PUPI® is the market leader in fiberglass crossarms in distribution with the broadest product offering and over 30 years of on-pole experience.

With systems designed for longer spans, heavy loads, and longer arms, PUPI is the market leader in transmission underbuild capability.

 

RUS drill patterns available across multiple product series including TS-1, TSS-1, and TPS-1, in typical underbuild lengths of 12’ to 16’. A wide variety of custom configurations are also available.
