The Helios LGM 125 is a high-quality ventilation cover designed to fit 125 mm diameter ducting. Featuring a sleek, white powder-coated finish, it is made from corrosion-resistant die-cast aluminium for durability and a clean appearance. The pitched louvres effectively obscure the view into the duct while allowing efficient airflow. Installation is quick and secure using the rear-mounted spigot, complete with clamping springs and sealing tape for a tight fit within the duct system.
