I have a kitchen wall which is made of wooden boards separated by U-shaped recessed channels. Rental house, so no drilling possible, but it occurs to me that if there were such a thing as an expanding fastener, something like an "inverse" clamp, it could pressure-fit into the channels and provide a movable anchor from which to hang pots and pans.
Does such a thing exist? I think it's different from slatwall in garages, as that has a lip on the upper side of each channel for the hook to grab onto. These channels don't have any lip, so it'd have to just be expansion that does the trick.
