Handua Plastic Damper Key for Round Ceiling Diffusers – HVAC Airflow Adjustment Tool Compatible with 6, 8, 10, 12 Inch Butterfly Dampers – Key Only, Damper Not Included

• ❗⚠️ [𝗜𝗠𝗣𝗢𝗥𝗧𝗔𝗡𝗧] ⚠️❗CHECK COMPATIBILITY FIRST: This key is NOT universal. It is specifically designed for butterfly dampers found in 𝟔, 𝟖, 𝟏𝟎, and 𝟏𝟐-𝐢𝐧𝐜𝐡 round ceiling diffusers (Handua style) that require a plastic adjustment tool. Please check your vent’s central mechanism before purchasing to ensure it matches the socket shape shown in the images.
• NOT FOR SCREWDRIVER SLOTS: Many vents require a standard flathead screwdriver for adjustment. If your damper has a visible metal slot inside, this plastic key will NOT work. This tool is strictly for key-operated damper mechanisms.
• DESIGNED FOR STANDARD DIFFUSERS: The key shaft is designed to reach the mechanism of standard residential round diffusers. Please Note: It may be too short for deep commercial vents, high-ceiling installations, or diffusers with extended necks.
• DURABLE PLASTIC CONSTRUCTION: Made from high-strength plastic to withstand regular airflow adjustments without stripping. Ideal for replacing lost or broken keys for compatible Handua and similar style round diffusers.
• EASY AIRFLOW ADJUSTMENT: Provides sufficient leverage to open or close butterfly dampers smoothly. When matched with the correct vent type, it allows for quick changes to your room's ventilation without the need for makeshift tools.
