Handled ascenders improve ease of climbing by giving you a large handle to hold and allowing the device to get a purchase on the rope rather than having to grip with your hand. This reduces the strength needed to grip the rope, and lets you have more endurance left to climb. Ascenders move freely up the rope but the cam is engaged when weighted, making these devices useful for ascent only. There are single and double handled ascenders available, and even double-cammed ascenders for use on doubled rope. The most popular hand ascenders are compact, single-handled ascenders which are easily stowed once you've reached your desired height and are ready to work the tree or descend.
Double-handed ascenders can be be used in the same manner as single-handled ascenders, but also offer advanced uses on doubled line. Either way, with two handles the user is afforded a more comfortable, powerful grip.

“ Incredibly useful item! I have been using it just about any time I need to pull a rope but I'd prefer to have a handle. This particular one is well made, grips securely, and advances smoothly. Having two lower attachment holes instead of one provides for additional flexibility in use. My only complaint is that the cam mechanism cannot be locked open and that it takes two hands to open the cam when no rope is present in the device. It would have been helpful if the mechanism operated similarly to the CMI foot ascenders. This is what I expected when I ordered the item, but the catalog photo shows the ascender from the backside and provides zero clues on the operation of the cam. ”
The CMI Twin Arborist Expedition Ascender is the first single-handled dual ascender designed to meet the needs of industry-leading arborist professionals. The "EXPTWIN" easily accommodates three rope techniques: the 2:1 doubled rope technique (DdRT), 1:1 single rope technique (SRT), and 1:1 twin line ascent (DdRT). It is intuitive and easy to use, has redundant safety features, and is the first ascender on the market to use one finger to actuate both cams for one-handed downward adjustability.
Weighs 15 ounces, measures 8" x 3.8", with MBS of 3,300 lb 1/2" capacity.

The rollers on this new chest ascender from CAMP of Italy are a big step up for ascending hardware. Normally this would be wear the rope could rub against the device. Placing these rollers here decreases wear and friction, making for a more efficient ascent. The Camp Turbochest is extremely lightweight, at only 3.9 oz, designed to lay flat against the chest, and works with ropes from 8-13mm (up to 1/2").
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.
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.
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.
