The IMPERIAL RG1451 is a louvered floor register designed for residential HVAC duct openings where appearance and moisture resistance matter. Constructed from high-impact polystyrene plastic, it resists warping and is easy to clean — making it a practical choice for kitchens, bathrooms, and other high-humidity spaces. The louvered face provides directed airflow from the supply duct to the room. The register measures 2.25 inches wide by 12 inches long and is sold individually. HVAC technicians and installers use this register as a finished cover for floor duct boots in new construction and replacement applications.
This register fits standard residential floor duct openings sized for a 2.25-inch by 12-inch boot. It is suited for applications where a complementary brown color tone is needed to match flooring or trim. Typical install scenarios include kitchens, bathrooms, laundry rooms, and other areas with elevated humidity where plastic outperforms painted steel registers over time.
Designed as an OEM-style replacement or new-construction floor register for standard residential HVAC floor duct boots with a 2.25-inch by 12-inch opening.
Floor registers are typically installed by HVAC technicians or general contractors during duct finishing. Before replacing an existing register, shut down the HVAC system and confirm the duct boot opening matches the register size. The register drops into the floor opening and is typically secured by its flanged border — no fasteners are required in most standard installations. Verify the finished floor surface is level so the register sits flush and does not rock.
