all straps are subject to damage from UV, and NONE are made to be on a tree for any amount of time
MOST all MFG"s don't recommend a stand be a tree for more than a few weeks, IF that~
I know FEW that follow this , most take for granted they can set up before the season and run them till ????
the main reason WHY MFG"s don' t suggest being on a tree long is, a TREE is constantly growing, and the amount of power the tree can place on welds and straps is HUGE, add is load stress when your IN the stand, and things can exceed the ratings for the parts they use in the stands!
SO< keep this in mind!
when buying straps, the game shouldn't be CHEAP< it should be quality
amount of leverage you can apply to a loc on stand when your in it can easy surpass what you weight and then some
I personally use 1500+ lb working load rated straps and use TWO to every stand
and I never leave straps up more than a month or so!?
old saying better safe than sorry!
known a few guys that had bad falls from stands, and only tales one to be sorry
