Bought WT46W563 heat pump dryer for our new Siemens this connection kit. Can me the positive reviews only agree. There were, as described, a drill and four screws here. I have the connection set mounted on a washing machine from Siemens. The drill had to cover our stainless steel washing machine no problem. However, the screws were unsuitable because the holes were a bit too small. Matching self-tapping screws, however, were quickly found and the frame easily mounted. However, the most important thing - the feet of the dryer to fit exactly in the guides provided the connection set. With the supplied closing pieces the whole structure sits absolutely sure spin. The also provided cover closes the gap between washer and dryer in a satisfactory manner. On balance I would recommend this product to any further !!!
