The DLC linear slot diffuser combines a discreet architectural profile with adjustable longitudinal fins for supply-air direction control. This galvanized-steel listing offers 1” slots in one-, two-, and three-slot configurations, with selectable lengths from 1 to 4 feet.

Key Features:

• Airflow Control: Adjustable longitudinal fins provide horizontal or vertical discharge arrangements and closure. Available patterns depend on the selected slot configuration.
• Slot Width: 1” slots, with one-, two-, and three-slot selections.
• Duct Openings: Listed opening widths are 2¼” for one slot, 4” for two slots, and 5¾” for three slots. Confirm cutout, overall dimensions, and mounting fit before ordering.
• Lengths: Current selections are 1, 2, 3, and 4 feet long. Contact us for longer runs, custom lengths, and section-joint details.
• Material: Galvanized steel with a painted finish. Contact us to confirm availability of an aluminum alternative.
• Frame Seal: Foam frame seal helps prevent dust marks around the frame.
• Related Components: Contact us for compatible plenum boxes and return-air linear configurations.
• Performance Selection: Confirm airflow, pressure drop, noise criteria, and throw for the exact 1” slot configuration before ordering. Family tables may include other slot widths; do not apply ½” slot values to this model.
• Finish Options: Baked electrostatic polyester paint. White is the standard color; Metallic Gray and Matte Black are additional listed selections. These are painted finishes, not an unpainted galvanized finish.
• Availability and Lead Times: This product is not routinely stocked. Configurations are normally made to order, including White. Made-to-order configurations have an estimated production lead time of 3–4 weeks. Shipping transit time is additional. Select your slot configuration, length, and finish to view availability for your exact configuration.

No substitutions without approval: If your selected configuration is unavailable, we may contact you with an alternative. We will not substitute the slot width, slot count, length, material, or finish without your approval.
