Tass Three Compartment Cavity Floor Box Kit


Midshires Comments

The TFB3 cavity floor box reduces the need for long wires and extension leads, by placing a floor box where the electricity is needed and will not get in the way of daily activities. They can be placed almost anywhere meaning you can have the outlet where ever you want, under a chair, under a table or even in the middle of the floor

Tass's Comments:

This cavity floor box has been designed to increase safety within the work place by reducing the amount of long wires that are exposed under desks. If you have a group of desks in the middle of a room, you would't need to use various extension cables to get power to them, instead, simply place several cavity floor boxes in under the those computers and it will prevent accidents from occurring.
