How long do Aaki Bonding Spools last?

We have never had one return in the 20 years we have been producing these. Depending upon normal wear and tear, we have sent out repair kits for handles, locking pins, cable and clamps, but the main spools body has turned out to be almost indestructible. Having said that, it’s still important to inspect, test and service them regularly as per your companies maintenance and testing program.
