While functional, these arrangements can be bulky, time-consuming to assemble, and often result in a less-than-ideal finished installation.\u003c\/p\u003e\n\u003cp\u003ePrinted in-house with a professional 3D printer from \u003cstrong\u003eUV stable acrylonitrile styrene acrylate (ASA)\u003c\/strong\u003e, our compact housing is precision-designed to securely accommodate two Thermobox dampers in a single integrated assembly. Internal locating ribs hold each Thermobox firmly in position, while a dedicated 25mm clearance zone allows the dampers to fully open and operate without restriction.\u003c\/p\u003e\n\u003cp\u003eThe housing features elongated oval duct connections designed to suit 200mm flexible duct, eliminating the need for large reducers and significantly reducing the overall installation footprint. Measuring just 310mm wide, 159mm high, and 243mm long, it provides a neat, professional solution where roof, ceiling, or bulkhead space is limited.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTo ensure optimal performance:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMount the housing perfectly level to ensure optimal operation.
