Available in standard and custom sizes, the Linear Slot Diffuser blends high functionality with architectural design that works across residential, light commercial, and commercial applications. Available in 1 to 4-slot configurations with 1/2", 3/4", and 1" slot widths. Standard and custom sizes available in any length. 100% Extruded Aluminum Construction No steel, no plastic, no stamping, no casting. Pure North American-made extruded aluminum resists rust, corrosion, and moisture—critical for the humidity and airflow demands of any HVAC system. At approximately 15% heavier than standard market alternatives, you can feel the quality difference the moment you handle it. Aerodynamic Ice Tong Louver Controllers Extruded aluminum pattern controllers deliver up to 180° of airflow direction control, allowing one-way, opposed, vertical, horizontal, or fully dampered configurations. Fully adjustable in the field so you can direct airflow exactly where you need it—and because the controllers are aluminum, not plastic, they resist corrosion and operate quietly over the life of the installation. 1 to 4-Slot Configurations Choose the slot count that suits your CFM requirements and aesthetic goals. Available with 1/2", 3/4", and 1" slot widths to match your specification and maintain a consistent look throughout the space. Single-slot units direct airflow in one direction; multi-slot models support broader coverage and higher air capacity. Continuous Run Capability Available in any length. Units over 84" are joined using alignment pins for a seamless, uninterrupted appearance—ideal for long open-ceiling runs in commercial and high-end residential spaces. Maximum pattern controller length is 60"; units over 60" will be supplied with multiple controllers. Supply or Return Design Remove the pattern controllers and the Linear Slot Diffuser transitions seamlessly into a return air grille—compatible with the same alignment pin system, maintaining an uninterrupted architectural finish from end to end. One product. One aesthetic. Zero visual compromise. Field Cuttable Ordered to length from the factory and cuttable on-site using a fine tooth, high speed carbon blade. A maximum of 3" can be trimmed from each end—up to 6" total—giving installers the flexibility they need during fit-out. For adjustments over 2", slide the retaining clip against the support. Remove end caps before cutting and reattach once complete. Multiple Mounting Options Three installation configurations to suit any project requirement: standard screw holes, concealed bracket (+10%), or lay-in with no mounting hardware. Every option delivers a clean finish appropriate for commercial and architectural applications. Faceplate Profile: 0.055" A slim, low-profile faceplate (DASL) that sits flush and clean against any ceiling or wall surface—purpose-built for modern interiors where every detail matters. White Powder Coat Finish (Standard) Clean, professional, and consistent. All Linear Slot Diffusers ship in a durable white powder coat finish. Custom colors, sizes, slot configurations, and mud-in options are available—contact the sales team to discuss your project requirements. Custom Sizing Available Produced to your exact specifications. Contact us directly for custom length, slot configuration, finish, or mounting requirements.

Use a fine tooth, high speed, carbon blade for cutting aluminum. A maximum of 3" can be cut from each end (X). For adjustments of more than 2" slide the retaining clip against support. Diffusers can be adjusted up to 6" by cutting both ends. Remove end caps before cutting and reattach once cut. Airflow Patterns One Slot Two Slots Show more
