I am off learning and teaching at Marc Adams School of Wood Working, expect shipping delays for next 2 weeks..
The KEEP-IT net tether is included with the K&R Net Keeper system but also offered here for those who want a second for another net. I have found too many nets along the path over the years to trust any attachment system. (Did I tell you about the net I laid down that started to float away.)
This is a retaining cord not a safety cord, it is not for heavy objects or personal protection.
