We have collaborated with Knappens for a long time and have great confidence in them. This is important as we as a pipe company are part of, among other things, large housing productions where everything must work perfectly. - The button always sets up, quickly fixes special pipe parts, lends machines if needed and helps in the best way, says Alf Höök. Otherwise, it is mainly their prefabricated sewer frogs that we buy. The drain frogs weigh a little and are precisely designed, which makes them easy to assemble and gives us great time savings, except that they are absolutely tight. We are very satisfied and have great confidence in Knappens, Alf Höök concludes.
