I am having trouble getting my new chain on to set well against a tree. I have had it now on three different trees. I have always used stands with straps instead of chains. Maybe i am doing something wrong. Just can' t seem to get it tight at all. I' ll get it tight then as soon as i sit in it the brace behind the seat at top pulls away from the tree at least three inches. One time it slipped on my buddy about 3 ft. down. [:@]. It is a river' s edge from cabela' s. Anyone help

Also is it to late in the year to be fooling around with moving treestands much?
