Back in the 90's there was an all aluminum hang on stand that had a gold anodizing on it with a flip up plastic seat. It used a chain and cable with 2 pink sponge balls to hang the stand. Basically you could set up the chain on the tree and just slide the stand over the cable to hang the stand. The sponge balls acted as stand offs so you could slide the stand on quietly. They were really light weight and had a nice big platform. I have one of them but there are no markings on it. I have got a piece of public land I want to use this on so I can take the stand out with me but leave the tree set up to hunt. It can be a long walk in sometimes and I don't want to leave my climber in there.
Keep me in mind if you want to get rid of them one day. I am going to see if I can make more of the chain attachments myself. I think I'll swap out the "S" hook for a quick link or better yet a padlock.
