3 + 1 System

Slab-On Grade and Retrofit

For 4'' slab-on-grade or retrofit applications

The HH Robertson 3+1 System offers you more capacity, less labor, larger outlets and a lower cost than underfloor duct systems. It can be fed with trench headers or with a cell feeder using large junction boxes, depending upon your needs. The 3+1 System offers a number of advantages, including:

• It can be installed in a single pour directly over a compacted fill. A concrete slab is not required. (A concrete slab IS required beneath the trench header.)
• The units' 4'' deep open top trench provides a larger feeder with significantly more feed capacity than 2'' cells or header ducts.
• Its full-size, 3'' deep cells provide much more wiring capacity than conventional underfloor duct systems.
• Large, 3-service, preset outlet boxes allow adequate wiring space within the floor, providing room for two duplex receptacles plus telephone and data connections to accommodate workstations easily.
• On-grade and elevated slab activations are identical in appearance since the outlet box covers are identical.
