EFLEX Square

EFLEX Square

Available in 5 sizes, with a range of innovative accessories.

EFLEX Square is an incredibly versatile system which enables simple and fast installation of buried cable routes.

EFLEX Square is flexible and stackable, removing the need for costly and cumbersome bend pieces.

The user is free to configure the cable duct stack to suit the project’s specific requirements, rather than being limited to a preconfigured layout.
