The height of the floor structure determines the choice for the type of outlet. A vertical outlet is generally preferred, but a horizontal outlet is an alternative for a shallow floor construction.
The choice of single or double anchoring depends on the floor material. For drains and gullies in concrete floors, Fenicrom® has designed a special flange for double anchoring, to prevent cracking and leakage along the drain or gutter edge.
If you have to install on an upper floor, an insulated drain or gutter is chosen, these are always with a vertical drain.
The degree of dirt collection in combination with the height of the floor structure determines the choice of model.
