The HAAS ascender is slick ascent tool which places a Climbing Technology at knee height. The bungee and snap on the top is connected to your Hitch Climber pulley (or another point in your system) and tends the device, while climber stands in the adjustable foot loop. With the HAAS ascent system, you can climb quickly and with a motion that many find more natural than the basic rope walker. By alternating between the HAAS and a foot ascender (on your dominant foot) you can basically run up the line!
The HAAS ascent system is available in regular or long, and works with ropes up to 13mm (1/2”) in diameter, in either SRT or DdRT systems.

“I reviewed the Haas a while back but after using it for several more months I wanted to weigh in again. It rocks. It is my go to for the second foot in ascent. People that have never tried SRT before make it look easy when I get them on this system . Folks that didn't like the coordination of the hand ascender with a foot loop love this set up. For me I like the hands on the rope instead of a hand ascender. The choice of the CT ascender makes more sense now since it takes up to 1/2 " climb lines. The Peztl basic is more svelte but does not accept 1/2 lines. To keep the knee ascender moving up with every step hook the bungy cord as high as you can in your system. ”

“This is a nice variation of a knee ascender. Works well under a Rope Wrench, Hitch Hiker, Unicender or on the tail of your DdRT system. The clever bungee system keeps the ascender moving up the line while clipped under the device on your climbing saddle. Alternate steps with the Haas and a foot ascender make for a smooth ascent. The slack in the line is pulled completely through any progress capture device on saddle with each step.
“The Tenex foot loop is adequate. Knee ascenders may make you kick out of your foot ascender unexpectedly. A locking style foot ascender or super smooth technique is the answer. Overall it is easier to use for most climbers than the hand ascender with a foot loop.”
This neat little ascender system can be added on to any rope climbing system using 7/16” (11mm) ropes. This kit was thought by veteran climber Gerry Beranek. In the doubled rope technique, this system puts a footstrap on the Basic which is in turn connected to the rope by a Prusik on a custom bungee lanyard. This bungee advances the ascender as soon as you step up with your leg that is in the footstrap. Pretty keen.

Improved Croll remains the best chest ascender. When used with a chest harness, the croll keeps you upright and well-positioned. Lays flat on the chest and can be easily installed on the line one-handed. Safety catch keeps rope captured.
Croll has a 7/16" (11mm) Max Rope size for the original, and is also available in a larger version which fits 1/2" ropes so that you can use this popular chest ascender on your favorite half-inch climbing ropes.
Replaces self-jamming knots like the prusik and Klemheist. The cam is a smooth bar, not toothed, which prevents the rope from being damaged when loaded suddenly. Because it accepts single or double rope, the Shunt is ideal for use in the secured footlock technique. 7/16" capacity.
Technical notice from Petzl for user's of the shunt as a backup device: Read the alert on Petzl's website.
Designed as an aid for climbing in the single rope technique, the chest roller helps by keeping the climber's torso connected to the rope. This enables the climber to recline comfortably without having to exert the stomach and arm muscles to keep the upper body close to the rope.
The chest roller harness is required in order to wear the chest roller. It is made of strong nylon webbing and has lots of padding and surface area to be soft and comfortable around the armpits and against the back.
