Modular code-compliant power. Connect up to six of our power units together to create a system of power for training spaces, workstations, or flexible spaces. Choose in-surface or on-surface. Pick the option that best fits your space: in-surface or on-surface. On-surface units can be mounted under or above table surfaces. In-surface units include a bezel that hides the mounting screws for a cleaner look. On-surface units can be mounted using a clamp (for a damage-free install) or installed using wood screws. Installation for in-surface units is a snap: Simply cut the opening, insert the unit, tighten the clamps, snap on the bezel, and plug it in. UL Spill Water Compliant. Passed UL 962A spill water test requirements so it can be used in a horizontal surface, such as a tabletop. This device complies with part 15 of the FCC rules. You will notice that our units (primary, middle, and end) all utilize a circuit breaker. UL962A Supplement SD requires that all furniture power distribution units for portable (moveable) workspace tables contain supplementary overcurrent protection. Tamper-resistant receptacles. Models have three tamper-resistant receptacles to keep little fingers away from danger.
