The HUUM Mounting Collar for HIVE Flow LS in black (Model HUU-H3018032) is designed to create a clean, finished transition where your sauna stove passes through a non-combustible wall. Precision-formed for a perfect fit, this collar helps center the heater opening, conceal rough cut edges, and maintain proper spacing for safe and efficient installation.

Constructed from high-quality stainless steel and finished in a sleek black coating, it is built to withstand high sauna temperatures while resisting warping, discoloration, and corrosion over time. The black finish offers a bold, modern look that pairs seamlessly with contemporary sauna interiors and darker design elements.

Sized at 24" x 23.2" (610 mm x 590 mm), the mounting collar provides full coverage around the through-the-wall opening while enhancing the overall visual presentation of your installation. It integrates smoothly with HUUM stoves and accessories, delivering both functional alignment support and a refined, professional appearance.
