Hubbell Incorporated HBL4PBI PLEX Portable Box Polycarbonate Ivory

Portable Polycarbonate Box for 4-Inch Square Boxes

The HBL4PBI is a portable device box built from polycarbonate in an ivory finish. It is designed for commercial-grade use in indoor, dry locations where a 4-inch square box is already installed. The unit provides four outlet positions and includes screw mounting hardware for secure attachment. An anchor hole and loop accommodate solid wire termination.

Mounting and Wiring Flexibility

The box accepts cable diameters up to 0.66 in and features triple wipe contacts for reliable connections. Break-off tabs allow split wiring configurations so three conductors can energise all four outlets. Screw mounting hardware is included, and the polycarbonate construction carries a UL 94 V-2 flammability rating. The design frees up space by consolidating multiple outlets into a single portable enclosure.

Upgrade from Basic Covers or Fixed Boxes

This accessory replaces simple cover plates or fixed enclosures when a portable, multi-outlet solution is needed on an existing 4-inch square box. The jump is worth it when a job requires split-circuit wiring, anchor points for solid wire, and a flammability-rated housing in one compact unit. It is not suited for outdoor or wet locations, nor for installations that demand more than four outlet positions.
