Caveat: it works. Only perfectionists are not necessarily happy (but who needs optical perfection at a wash column?) To connect different equipment manufacturers to a column is of course an issue, especially if the unit below also has an oblique orifice. To have available the whole area around every 4 feet of the dryer on the washing machine (which I recommend at the very high weight of a heat pump dryer), you have to cheat a little and let the front end panel of the connection set something on the front edge (2-3cm) are the washing machine , This is but also in the operation of the washing machine no problem. Visually, it remains within the limits of what is possible (for this info for those interested). Of course, there are other solutions, but saw after I "walk" even a washing machine with a broken damper, I feel better with a bolted solution. The product is whether the price Top. If you want more quality, also has to lie down more money. This product fulfills its purpose and the documentation as well as the accompanying drill with stop are top. The drill can be put back into a slot even within the frame, so that it is again ready to hand when sometime eg a new washing machine is due. I call that well thought out.
