Hefty Tray

The strongest choice for industrial environments

image

Hefty tray was developed to carry the loads of large power cables used in heavy industry. It supports up to 20 foot spans. And due to the thru welded rungs it is much more resistant to side wall rotation. These features come together to give you a system that is an easy choice for projects with a high short circuit requirement.

Hefty tray allows you to achieve the highest possible current capacity for your conductors. The open top and bottom of a Hefty tray allow for maximum airflow. The lower operating temperatures also contribute to a longer service life.


Easy to Install

Hefty Tray is a simple and straightforward system to install. You need a smaller electrical crew to complete the installation. And pulling cables is simplified by the fact that no tap boxes are required. Hefty tray is a wiring method that allows you to pull cables with minimal risk to damaging the conductor insulation.
