CMI Ultrascenders are made of extruded aluminum with corrosion-resistant chrome-moly steel cams, rated at 4500 lbs. They feature a molded grip and room enough inside to grab like a handle on the rope.

Here we offer them with our New Tribe Ascender straps permanently sewn on. With New Tribe Ascenders, any person of ordinary strength can go straight up a rope in complete safety, stopping to rest at any time. The large stirrups make it easy to insert or remove your feet, so you can quickly switch back and forth between climbing the rope and climbing the branches. The screw link makes it easy to connect the straps to your climbing saddle, and allows you to use the ascenders separately when you want to.
