Wall collar AWENTA RM120 metal, white — wall collar for ventilation duct, model RM120

AWENTA RM120 metal wall collar in white is designed to create a sealed and neat passage for round ventilation ducts through walls. The collar provides a compact flange connection between the ductwork and the wall opening, suitable for both residential and light commercial ventilation systems and extractor fans. The white finish offers a discreet visual appearance while the metal construction ensures mechanical durability and a stable mounting surface.

Advantages

The metal construction gives the wall collar rigidity and resistance to deformation during installation and use, while the white coating provides corrosion protection and a clean appearance that blends with typical interior and exterior finishes. The compact flange profile simplifies fitting into limited wall cavities and around existing frames, and the product is dimensioned to match standard circular ventilation ducts for secure attachment.

Suitable for

• Creating a sealed passage for round ventilation ducts through masonry or partition walls
• Connecting extractor fans to external ducting
• Retrofit installations where a compact wall flange is required
• Residential kitchens, bathrooms and small commercial ventilation outlets

Key specifications

• Material: metal construction with protective white finish
• Shape: round collar designed for circular ventilation ducts
• Finish: white coated surface for visual integration and basic corrosion resistance
• Application: wall mounting to create a duct passage and flange connection

How to use

Cut or prepare a circular opening in the wall matching the collar diameter and clear the surrounding area of debris. Insert the AWENTA RM120 collar through the opening so the flange sits flush against the wall surface, then secure it with appropriate fasteners for the wall material (screws, anchors or masonry fixings as required). Connect the ventilation duct to the inner collar tube and fasten the joint with clamps or sealing tape to ensure an airtight connection. Check alignment and sealing before completing any finishes around the collar.

Usage recommendations

Use fasteners and sealing materials suitable for the wall substrate and local ventilation standards. For improved airtightness, apply a thin bead of suitable sealant between the collar flange and wall surface where required. Confirm that the collar diameter matches the duct size and that any fan or grille attached is compatible with the compact flange profile.
