For sale is a pair of Petzl aiders. I purchased these about 5 years ago to aid through hard sections on multi pitch climbs. I have only used them once and they are practically new. They are 5 steps with a half step at the top. I will include the carabiners (pictured). I will ship to any place in the lower 48 on my dime. $60 PayPal only. If interested contact me at . Thanks for looking!
