Hey guys. I'm looking for the replacement cables for a couple of my climbers. These two particular stands have the wire that is covered by a black tube. They have a hard piece of wire through them to hold the shape. Now, on two stands I need the covering for the cable. On one stand I need the wire. I'd like to just find them put together. Anyone know where I can find them? Otherwise I need to put them together myself, which seems to be a less safe option. Help! Thanks!
