You may want to invest in a pair of these..19.00 on Amazon...
I just about had a costly accident this year..A friend on here { Can see the off season forum..named Mr. Davis.} told me about this product WOW!! they work..it's like your stand is bolted to the tree.
NOTE..I pull the stabilizer straps snug when my butt is on the rail when I'm as high as I want to go..this is much safer,,,and much more secure.
