Any recommendations for a cost effective solution here? When I lift the floor it's basically a void and dirt below so I want to protect the cables from damp & rodents. In additon the ability to re-cable without lifting the floor again will be a big bonus. This is specifically for the run to the floor mounted PJ to the side wall where the rack will sit. EDIT:- No sooner had I written this than an obvious solution came to me. It has to be the waste pipe type pipe you fit under a sink surely? Screw together sections and water tight too. I've left the thread here to see what others would do. Cheers, Mark.
