About this item

  • Nylon
  • Made in the USA or Imported
  • Double tube System allows 30" of in-line bungee to be contained within the unit for over 30" of elongation
  • Versatile ascent System has zero set up and can be used by multiple users without adjustment
  • Snap is tied just above the Ascender, extracting out up to 30" to eliminate any set up as well as any "dead spots" in the return action
  • Designed to maximize friction reduction
  • Bungee returns up a second channel where it is tied to a snap and is replaceable in under five minutes with no tools


Patented design improves on the already ingenious Haas ascent system by giving you an additional 18" of bungee in the system for a total of 30". designed to maximize friction reduction with a bungee that terminates at the top of the velox, travels down the channel to the bottom where it wraps around a shiv with stainless steel sealed bearings inside a machined aluminum block.

other than being the shorter model, I 1st bought not knowing it was short, bought it as i wanted to have the color that was more visible.. as with the black and blue regular size model it functions great and though i had a free replacment i have this for a back up, will just buy a new bungee cord later to extend it when/ if needed

If you climb SRT this is a must have! Made it a breeze getting up. I ascended 50 feet or so 15-20 seconds. It was awesome!

Pissed…. Traveling due to work commitments and now back at home.. Had a chance to catch up on so many things including reviewing this climbing assist…. Return window has now closed due and i am just finding out that i have been sent the short version.. NO FREAKIN’ where - can i find where it states it is the SHORT VERSION.. So now i am stuck with a device that I can’t really use due to my size.. Not nice to say what I am really thinking just now….
