A two-handle ascender built for arborist SRS climbing.
The CT Quick Arbor double hand ascender from Climbing Technology gives you two handles on one rope clamp, so you can push with both hands on an SRS ascent. Climbers who spend a lot of time ascending often find the two-handle grip less tiring.
A standard hand ascender has one grip. The Quick Arbor adds a second handle so both hands can drive the device up the rope, spreading the effort and helping you keep a steady rhythm.
It pairs well with a foot ascender for a full rope-walking system. Compare other handled ascenders in ascent and descent.
On long ascents with heavy gear, a double-handled ascender can make a real difference to how fresh you feel at the top. Try one before buying if you can, since grip and fit matter.
Follow Climbing Technology's instructions for rope diameter and connection points, and test on the ground first.
An ascender is not a descent device. Life-support gear must meet the applicable standard (ANSI Z133 and the manufacturer's instructions), be inspected before every use, and be used only by trained climbers. Inspect the cam teeth, spring, safety catch and frame before every climb.
Keep the cam clean of sap and bark so it grips evenly, and check that the handles have not cracked from drops or impacts. Store the ascender in your climbing bag away from heavy hardware.

Some climbers prefer the two-handle grip for long ascents. It comes down to your system and feel.
No. Switch to a descent device before coming down.
