For sale is 100 ft of 1/0 neoprene welding cable. Very high quality stuff, surplus of a major government funded lab. Was used as a grounding cable. Has a grounding attachment on one end. It has one gash (see photos) and other minor nicks. Nothing that a few inches of insulation tape would not fix.
The length stated is approximate, I counted my steps (33) and I know that my step is slightly over 3 ft. I am reasonably confident that it really is about 100 ft.
This stuff is HEAVY, about 80 lbs, hence the shipping charges.
