Duck ascender

Great product must have for any small diameter tree tether or climbing rope

Matt Smallwood
Duck ascender

This things works great! I had my prisik knot slip in the rain and decided to go with this ascender and now I have no worries of it slipping. It bites great on my lineman and tether!

The issue with this product is once you have one, you need 3. Great product and suuuupppppeeerrr useful

More important than you think

I can't say enough about how these units make saddle hunting easier. Are they absolutely required? No. Would I change out every prusik know with a carabiner and ascender? Absolutely!!

Essential for lineman's rope

I originally got this for my bridge rope but found out quickly that it was much better utilized on my lineman's rope. It makes climbing a tree as it narrows much much easier and adjusting the rope a one handed task. If you don't have one for your lineman's rope do yourself a favor and get one asap.
