EFLEX Square Duct Advantages

Each EFLEX Square unit has a minimum bend radius up to 10 x its inner diameter. No separate bend pieces are necessary. Built-in male and female push-tight connectors ensure watertight interface.

Units are stackable, resulting in fast and simple installation, even in areas with limited space.

Buried at 300mm, EFLEX Square can handle loads equivalent to that of a 25 tonne truck. The shallower burial depth means a smaller trench is required, further reducing installation time and cost.
