FLOOR POCKETS Whirlwind supplies several sizes of floor pockets to protect and provide access to audio, video, and AC connectors. Constructed of 11 gauge steel, the FP-1 and FP-2 permit flush installation for safe, reliable connections. The optional back boxes (FP-1BB and FP-2BB) have three sets of knockouts on each side. Each unit incorporates a black carpet trim ring with a beveled edge. Two cable-clearance slots in the door allow it to close over cables when in use. The FP-1 mounts four XLR connectors, the FP-2 eight. Nominal Outside Dimensions: FP-1: 6" x 6" x 4" FP-2: 12" x 6" x 4" The FP-3 has a rugged 3/8" (10mm) non-skid, cast iron tread plate with a hinged door secured to a steel back box. The finish is a baked black flat enamel. An angled insert panel, the FP-3INS, is required for mounting connectors and must be ordered with the FP-3. It can be factory punched and loaded to your specifications for an additional charge. All FP Series floor pockets are UL-listed and CSA approved in Canada. FP-3 Nominal Outside Dimensions: FP-3: 13.5" x 10" x 9.5" FSR Floor Pockets are designed to fit the needs of power, audio, video, and data applications and provide a practical solution for cable storage while maintaining easy access. The cover has a large, lift-off section for access to internal cables and connector plates while a smaller trap-door creates a cable exit. The sturdy 11 gauge cover lies flush with the floor while the brass or aluminum edging is only partially seen through the carpet. Two angled brackets are provided with a single, double, and a four gang opening for connector mounting. Standard wall plates are additional.
