The Assembly is, however, unfortunately directly to the transverse slats of the bed. That is, if the holes are even in it, then that should also fit. On the product photos, the tunnels are always excited lovely. To achieve this, the tunnel must be very tightly fitted, possibly with some tension. That is often 2nd person and thick short screws + pre-drilling (please not too deep!).
After 14 days, the substance has then yielded to something and you probably have to tighten again. This is stupid!
Advantage of this installation: it has room for maneuver concerning the tunnel height.
Otherwise the substance is very nice and not so terribly thin. It smells and stinks nothing. Colors are super. Material quality also.
Care also with the rod system: here pipes were used, which have a pleasant stability (if too hard: ouch, fiberglass rods: too unstable).
At the low tunnels the substance is often not as nice or the level is low or the length short.
