Product Usage Instructions

• To calculate the total box volume for the Ratchet-Pro 881 Series Floor Boxes, use the displacement of the largest uncut section remaining. The box height options range from 3 inches (76mm) to 6 inches (152mm). Ensure that the concrete pours are at least 4 1/2 inches (114mm) deep for proper installation. These floor boxes should not be used when concrete is the finished floor; they are only suitable for tile, carpet, or wood-covered floors.
• The Ratchet-Pro Series Floor Box Wire Fill Capacity Charts provide information on wire fill calculations for different box heights. The charts specify the available volume for conductor calculations based on the floor box model and conductor type. Refer to the provided website www.legrand.us/wiremold for the latest specifications and additional details about the Ratchet-ProTM Series Floor Boxes.

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.
Ratchet-Pro Series Floor Boxes provide access to power, A/V, and communication services to open-space areas.

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 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 allowing for easier wire pulling for dual-service.

• Graduated cubic inch markings on the interior of the box. Allows for 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-OG floor boxes (sold separately) a greater capacity of pre-terminated cables can be brought in shallower concrete pours.

•  Slab-on-grade versions. Boxes offered in PVC and steel with a special fusion bonded epoxy corrosion-resistant paint, enable the boxes 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 device.

• Durable mudcap. High high-impact mudcap protects 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 Wiremold 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 UL514C for scrub water exclusion test for carpet and wood floors.
