Arbpro's new knee ascender system uses a self-recoiling steel spring to advance the integrated rope grab. The Gemini includes two lower straps: a footloop and a snap to connect to boots with a connection loop on top of the foot, like the Arbpro EVO 2.
Details
On the bottom of Gemini Knee, a foot strap can be installed to help the climber advance on a static line. Unlike other knee ascenders, the Gemini Knee features an efficient spring made out of steel. This provides a strong and constant self-advancing force to carry the ascender up the climbing line.
Compared to other systems that use bungee, Gemini Knee offers enhanced performance that's compact and stores easily. The strong recoil effect from the spring does not require long and uncomfortable bungee slings that sometimes need to be placed over the climber’s shoulder to provide the necessary pull.
Gemini Knee has a locking cam on the ascender. Lock it to prevent accidental kickout or open it to get the climbing line out of locking cam quickly and easily.
Gemini Knee comes two lower straps: one with a snap for boots with EZLoop ™ and one with an adjustable loop for standard boots. Install whichever one fits your needs.
