Collection: Single & Double Deflection Grilles & Registers

Our single and double deflection grilles and registers are designed to provide reliable airflow distribution and directional control for residential and commercial HVAC systems. Available in a range of sizes and configurations, these HVAC air grilles and registers can be used for supply air applications where controlling the direction and spread of conditioned air is important. Single deflection grilles feature one set of adjustable blades for directing airflow, while double deflection grilles combine two blade sets for greater control over both horizontal and vertical airflow direction. Not sure which configuration or blade orientation is right for your application? Read our guides on horizontal or vertical blades for single deflection grilles and front horizontal or vertical blades for double deflection air grilles for a detailed explanation of the differences and how to choose the right configuration for your project.
