As well as floor drains, ETU also offers various drainage channels for indoor use.
> Standard channel (type 1)
> Standard channel with additional outwards chamfering (type 2 thin mortar bed flange)
> Standard channel with file protection angle-frame (type 3)
> Special channel shapes
Each drain channel is individually manufactured and adapted to the structural circumstances (lengthways/crossways slope or no slope). Depending on area of use, different cover variants can be used.
