Ascenders & Descenders  

Ascenders and descenders are all safety components designed to help arborists climb trees. Rope grabs are designed to grab the line and arrest a fall if an arborist puts weight on their harness. Ascenders and descenders help climbers scale up and down the tree without putting in too much effort.

We have a collection of high-quality ascenders, descenders, and rope grabs made from brands like DMM, ISC, Stein, etc. All products are certified by authorities, and tested to withstand different conditions. They’re made from resilient materials so you can expect them to last for years with proper maintenance.
