SpiroFlex rosette polished Ø125 for ventilation ducts, model SX-WO125RS

SpiroFlex rosette polished Ø125 (model SX-WO125RS) is a metal finishing accessory for round ventilation duct openings with a nominal diameter of 125 mm. Designed to be mounted on ducts, wall or ceiling penetrations, the rosette provides a smooth, polished edge that conceals the cut margin and secures the duct connection. The compact, durable construction is suitable for residential and light commercial ventilation systems and helps create a neat visible finish around circular openings.

Advantages

The polished metal surface resists corrosion and is easy to clean, while the rigid form keeps its shape after installation. The rosette simplifies alignment of Ø125 ducts and reduces the need for additional sealing trims. Its low-profile design minimizes protrusion from walls or ceilings and delivers consistent aesthetic integration with existing ventilation components.

Suitable for

• Finishing round Ø125 ventilation duct penetrations in walls and ceilings
• Residential ventilation systems, including kitchen and bathroom exhausts
• Light commercial ventilation where a neat visible finish is required
• Situations needing a quick way to conceal and protect duct edges

Key specifications

• Nominal diameter: 125 mm
• Material: polished metal
• Design: low-profile rosette for round ducts
• Compatibility: for circular duct openings with Ø125
• Application: wall, ceiling or duct-face mounting

How to use

Position the rosette over the prepared Ø125 opening so the polished face covers the cut edge. Slide the rosette onto the duct end or press it against the wall/ceiling penetration and secure according to the mounting method appropriate for the installation (e.g., fix with screws through the duct flange or use sealant where a flush fit is required). Ensure the rosette sits evenly and that any gaps between rosette and surface are sealed if airtightness is needed.

Usage recommendations

For best results, verify that the duct end is deburred and free of sharp edges before fitting the rosette. Use corrosion-resistant fasteners and a compatible sealant if the installation requires moisture or airtight sealing. Periodically inspect the visible finish and clean with a soft cloth and mild detergent to maintain the polished appearance.
