Aw man sounds like a hole punch that rivets a hole guard onto it. Ill see if i can find one of these thanksWatched a neat little vid on YouTube the other night on just this topic , the guy had bought ( I can’t remeber the name lol ) but basically a hole punch that put like a metal ring doughnut on the pot he done four 1 opposit the other then ran gardening wire through and round thus creating a nice anchoring point for attaching to , easy work and A dam good idea
