Grilles, Registers & Diffusers

9 products

Grilles, registers, and diffusers connect to the ventilation system inside a building and create a termination point for ventilation ducts. They offer an appealing appearance while directing airflow and preventing objects from entering the HVAC system. Some units feature adjustable blades that allow users to redirect or block airflow as they see fit. Grilles cover the ends of HVAC ducts and block objects from entering. Registers direct or block the airflow exiting the duct, increasing occupant comfort. Diffusers spread conditioned air throughout a space to ensure even heating and cooling. Grille, register, and diffuser accessories provide additional functionality to existing components or help users to install them.
