This Quad Stringer Box works well when customers need compact branch power in a very small format. Because it combines a Hubbell HBL3521C plug, 12/5 cable, and two color-coded duplex receptacles, it gives users a practical way to place power where a larger distro would be unnecessary. In addition, the polycarbonate enclosure helps keep the unit lightweight, while the split-tab red duplex supports more flexible circuit use. Comparable stringer boxes also serve temporary applications where a full rack is not practical.
