My son in law helped me with these 2 lock-on type tree stands.They are made of bed frame angle iron,some leftover expanded metal,and other scrap pieces I had around the shop.All I bought was the chain , cable clamps,and a little paint. The cam action really works very good and they are solid as a rock.I mount them on the tree with the floor up,then,after chaining it,pull the floor down and it tightens up nice. God Bless
