HH Robertson in-floor cable distribution systems maximize
flexibility and sustainability without sacrificing safety.

These systems safely route telecom, data and power cables through trench headers and steel cells that are also the structural support for the floor slab.

Sustainable Design. HH Robertson systems conserve materials, are fully recyclable, last the full lifespan of a building and require no maintenance.

Simple Set-up. HH Robertson systems deliver hassle-free yet secure access to all cabling and the activation of in-floor outlet boxes without the use of ladders or distracting core drilling required with ceiling plenum systems.

HH Robertson systems contain no harmful substances and shield building occupants from dangerous plenum cabling ingredients, like lead.

Whether it's HH Robertson Q-Floor/Taproute™ for steel frame construction, Cellcast™ for concrete frame construction, or 3+1™ for slab-on-grade construction, you can specify an HH Robertson system to meet the requirements of any project.
