Old inner tubes, MTB type, , I tape and zip tie the cut ends of the tube to the chain..
my Abus chain lock came with a nylon cordura hose like sleeve, but it was Red,
and promptly showed grease, from chain contact, and so I deployed an old inner-tube..
Places that you leave the locks know your scheme, so wont clear the rack of your left behind chain?
Campus security may do that in the summer, on College Racks, grinder disc cut off old locks
and Auction off abandoned bikes..
