## Long description

Wall collar (round) AWENTA KO100-27 for 100 mm duct openings is a circular finishing and sealing component intended for ventilation and exhaust installations. It is designed to provide a tidy transition between a wall surface and a 100 mm diameter duct or pipe, supporting a secure and stable mounting while helping to reduce dust ingress and drafts at the penetration point. The collar is suitable for applications in residential buildings and light commercial environments where a compact, round wall finish is required.
Advantages
The AWENTA round wall collar offers a precise fit for 100 mm ducts, enabling a consistent and professional appearance at wall penetrations. Constructed for straightforward installation, the collar supports stable attachment of ducts and helps maintain airflow integrity by limiting gaps around the pipe. Its design reduces dust and air leakage around the installation and facilitates easier maintenance and cleaning of the duct opening.
Suitable for
Finishing circular ventilation duct penetrations in residential walls
Exhaust pipe terminations for kitchens and bathrooms
Light commercial ventilation installations with 100 mm ductwork
Retrofit or replacement of worn or damaged wall collars
Key specifications

Shape: round
Function: finishing and sealing wall penetrations

How to use
Prepare the wall opening to match the 100 mm duct diameter and ensure the surrounding surface is clean and free of debris. Position the AWENTA KO100-27 round collar around the duct at the wall penetration and align it so the flange sits evenly against the wall surface. Fasten the collar according to the mounting method appropriate for the wall material and the ventilation system — for example, using suitable screws or anchors — and verify a stable fit. Seal any remaining small gaps as required with compatible sealant to reduce drafts and dust ingress.
Usage recommendations
Use the collar in conjunction with properly sized 100 mm ducting and follow local ventilation codes. When installing in damp or high-humidity areas, ensure fasteners and sealants are suitable for the environment to maintain a durable installation.
