Securlec Louvred Ducting Grille with Spigot - Grey 150mm / 6 Inch

The Securlec Inlet/Outlet Fixed Louvre Grille is a 150mm (6 inch) louvred ducting grille designed to sit at the external end of a round ducting run, letting air pass through freely while keeping wind driven rain, leaves and debris out. Its angled louvre slats make it a practical louvre vent cover for kitchen extractor ducting, bathroom and utility room ventilation, and general purpose external ventilation on residential, commercial and industrial buildings.

Key Features

• 210 x 210mm grille face with a 150mm spigot for a snug fit onto round ducting
• Louvred design that promotes steady airflow while shielding the duct from rain and debris
• Durable, weather resistant grey plastic construction built for long term outdoor use
• Versatile enough for residential, commercial and industrial ventilation projects
• Suitable for kitchens, bathrooms and utility rooms as an essential extractor vent
• Can be used on ducting runs from electrical and gas appliances

How to Use / How to Fit

Cut the round ducting to length and core or cut a hole through the external wall to match the 150mm duct diameter. Push the spigot on the back of the grille into the end of the ducting, adding a bead of silicone sealant around the joint if you want a fully weathertight seal. Once the spigot is seated, offer the grille up to the wall so the duct passes cleanly through the cored hole, then screw the outer flange to the external wall face using suitable fixings. Check that the louvre slats are angled downward on the outside so that rain sheds away from the ducting rather than running back in.

Frequently Asked Questions

What is a louvre grille?
A louvre grille is a ventilation cover made up of angled slats that let air flow through an opening in both directions while blocking rain and larger debris from getting in.

How do you fit a ducting grille like this one?
The spigot on the rear of the grille pushes into the end of your round ducting, and the outer flange is then screwed to the external wall around a hole cut to match the duct diameter.

Can this be used for a kitchen extractor fan?
Yes, this louvre grille is designed for essential kitchen, bathroom and utility room ventilation and works well as the external terminal for a kitchen extractor duct.

Does it keep rain out of the ducting?
The angled louvre slats are designed to shed wind driven rain away from the grille face, helping to stop water running back down into the ducting while still allowing air to pass through.
