The Hart Cooley 683-10x4 is a three-way sidewall and ceiling supply register designed for residential and commercial HVAC systems. It fits a wall opening of 10 inches x 4 inches and has an overall face size of 11-5/8 inches x 5-5/8 inches. This register is part of the 683 Series, a trusted line used by HVAC technicians and contractors across a wide range of installations. The all-steel construction gives it the durability needed for long-term use in demanding environments. The white finish blends cleanly with standard wall and ceiling surfaces, making it a common choice for both new construction and retrofit projects. This register works for ceiling or sidewall applications, giving installers flexibility when laying out ductwork. It is especially well-suited for shallow duct installations where depth clearance is limited. The unit measures only 1-5/8 inches in depth when fully opened, which allows it to fit in tight spaces without sacrificing airflow performance. The three-way deflection design lets HVAC professionals direct conditioned air in multiple directions from a single register, improving comfort and coverage in the room. The fins are spaced at 1/2 inch intervals and set at a 40-degree angle, which helps distribute airflow evenly across the space. A multi-shutter valve with interlocking louvers provides positive shut-off capability, allowing full control over airflow at the register level. This is useful when balancing air distribution across multiple zones or rooms. The interlocking valve louver design ensures a secure close without gaps, preventing unwanted airflow when the register is shut. HVAC technicians will recognize the 683 Series as a reliable, straightforward supply register that installs quickly and performs consistently. It is compatible with standard rectangular duct openings and is suitable for residential, light commercial, and retrofit HVAC applications.
The Hart Cooley 683-10x4 supply register delivers three-way airflow control, shallow-depth installation capability, and solid steel construction in a 10 inches x 4 inches wall opening size. It is a dependable choice for HVAC contractors handling sidewall or ceiling register installations.
