Single & Dual-Service Round Floor Boxes
Wiremold® Ratchet-Pro™ Series Floor Boxes provide single- and dual-service capability in a variety of easy-to-install round floor boxes. These designs allow the flexibility for providing power, A/V or communication services to open-space areas in an aesthetic solution.
Applications include malls, shopping centers, department stores, airports, hospitals, and office buildings. Ratchet-Pro™ Series Floor Boxes are cULus- listed for use in both on-grade and above-grade concrete construction.

Features & Benefits

Ratchet adjusting ring. Allows for quick and easy installation without gluing, as well as removal of cover to activate at a future date for dual service*. 10˚ of flexible adjustment allows the cover to conform to the surface of the concrete pour, which significantly reduces labor costs.
Parallel conduit hubs. Allows for conduit feeds to be parallel for both power and communication cables. Reduces labor and material costs by eliminating the need for 90˚ bends and allows for easier wire pulling for dual-service.
Graduated cubic inch markings on the interior of the box. Allowsfor quick and easy determination of cubic inch capacity – no need for calculations.
Complete line of brass brushed aluminum and polycarbonate activations. Provides a wide selection of device and aesthetic options.
Corresponding graduated cubic inch markings on the divider. Labor savings are provided by easy separation of services. Individual compartment capacities are indicated.
Individual conduit reducers & plugs. Reduction in labor savings by providing a direct reduction to support smaller conduit feeds.
Multiple-size conduit feeds. Conduit feed ranging from 3/4″ to 2″ trade size openings to allow for more flexibility and capacity.
2″ conduit hub. By using 2HUB with the RPSFB and RPSFB-OGfloor boxes (sold separately) a greater capacity of pre-terminated cables can be brought in a shallower concrete pour
Slab-on-grade versions. Boxes offered in PVC and steel with a special fusion bonded epoxy corrosion resistant paint, enables the theboxes to be installed in on-grade applications without the need for additional vapor barriers.
Streamlined design of divider. Labor savings from ease of cutting using a utility knife, no hacksaw or tape measure needed. Also allows for more room to splice wires.
Dead-Front” protection with the RP Series Covers. Slide covers snap back into place when the receptacle is not in use to prevent dirt and debris from entering the device.
Durable mudcap. High high-impact mudcap protects the box from damage when heavy equipment such as scissor lift trucks come in contact with the box during installation.
TopGuard protection. An integral design that keeps out water, dirt, and debris from the power or communication compartment. Whenever you see the TopGuard protection icon applied to any Firemold product, you will know that the product meets and exceeds the new UL scrub water exclusion requirement.
UL Listed to U.S. and Canadian safety standards for tile, terrazzo, and the new UL requirements under UL514A and UL51 scrub water exclusion test for carpet and wood floors.
