The installation couplers EnstoNet XL are characterised by their modularity and ergonomics. It is easy to match the components based on their housing shape and connect them with one another – even without seeing them. The couplers are reusable and have a long service life, which supports sustainable use. In addition, they are colour-coded according to their application areas and structurally incompatible with components for different applications so as to ensure safe and easy installation.
