You were very helpful on that one (Channel nuts) Thanks Again!
Now what I can't find is the floor channel cover in black PVC!(or any color) This is 1and5/8" channel and the cover width is 2and1/2". It snaps into the exposed channel.
This would seem to be a common item for trailer or medi-van modification. (I believe the economy caused many of these types of businesses to go under, at least in my area)
