Verplas 150mm External Gravity Grille Multi-Colour
The Verplas VKC292 is a 150mm external gravity wall grille with a gravity-operated shutter that opens under positive airflow pressure and closes when the fan stops — preventing back-draught, insect ingress, and weather penetration. Designed for external wall mounting at the termination point of a 150mm duct run, it is available in multiple colours to suit different property exteriors. Overall grille dimensions are approximately 185 × 185 × 55 mm, providing a neat, low-profile external finish.

Colour Options: The VKC292 is available in White, Brown, Grey, and Black — select the variant to match your property's exterior brickwork or render for a discreet, integrated appearance.
External Fitting: The grille should be fitted to the exterior face of an external wall, with the duct spigot passing through the wall to connect internally to the 150mm duct run. Ensure the grille face sits flush against the wall and seal around the perimeter with an appropriate external sealant to prevent weather ingress.
Key Features
Gravity Self-Closing Shutter
The gravity-operated louvre blades open automatically when airflow is present and fall closed when the fan stops — preventing back-draught, insects, and rain ingress without a spring mechanism.
150mm Round Spigot
The integrated 150mm round spigot connects directly to System 150 rigid duct, telescopic pipe, or flexible hose at the wall penetration point.
Four Colour Variants
Available in White, Brown, Grey, and Black for a discreet match to the property exterior — specify the required colour variant at the time of ordering.
185 × 185 mm Face Plate
The compact square face plate provides a neat external appearance with a generous free area for the duct diameter.
Weather & Pest Resistant
The gravity shutter closes under its own weight when no airflow is present, preventing wind-driven rain, insects, and small birds from entering the duct system.
System 150 Compatible
Designed to terminate Verplas System 150 round duct runs at the external wall, compatible with all 150mm VKC-series duct fittings.
