Paliston Climbing Hand Ascender for Rock Climbing Arborist (Right and Left) for 8~12 mm Rope

Connect some foot loops to these things and you are set up for success! Climbing up, climbing down, both are a breeze with these things to assist you! Love them! Working on the roof was a breeze with these.

Never climbed a mast before so this is my first experience. I used these in tandem with a climbing rope, climbing harness, climbing strop and some rope. Very easy to slide the handles up and down. Had to be careful on the way down not to put the top handle too close to other otherwise under load with the rope stretch you could move the bottom one (this isn't a fault of product, but a pointer). Really felt safe with them, wouldn't climb without these two now

High quality and worked well and without issue. They were used to assist climbing a 38° slope out of a mineshaft.

They seem to be very well made, I'm happy with the price for the set

Easy to use and safe. Used these to climb about 45' up a giant oak tree I pruned on my property.
