Self-braking descenders offer additional control and are useful in rescue, climbing, and as part of a basal anchor in SRS to allow lowering of the climber from the ground.
Feedback gathered from highly qualified and experienced 'Pro' users highlighted a demand for a device which does not incorporate a panic-brake function. Enter the D4PRO! The D4PRO Descender is the same great Work/Rescue Descender, but without the panic brake.
This can be particularly useful on longer descents and in rescue/belay applications, where a broader 'sweet spot' is welcomed.
D4 PRO Details: WLL 529 lb (240 kg), weighs 24 oz, and works with ropes from 10.5mm to 11mm (7/16”).
This Descender from ISC features some unique features for a handled descender. The handle is aluminum and coated for grip, and designed to rotate 360°, making it easier to use and switch between allowing the rope to run and locking the device. Each station in the rotation is accompanied by a “Click” so that you have the audio feedback in addition to the feel of switching the position. Features an anti-panic brake if the handle is rotated too far by an inexperienced user.
These devices have great video and manuals on the D4 descender page.
D4 Details: 5 1/2” x 3 1/4”, weighs 23 oz, and works with ropes from 10.5mm to 11.5mm (7/16”).
D5 Details: 240 kg/500 lb WLL, weighs 29 oz, and works with ropes sized 12.7mm (1/2”).
Rated: Disappointing Review by:
“ I purchased this as a climbing descender. I think the "descend" position is to small and it goes into the "panic" position too easily. I can't keep it out of the "panic" position when trying to descend. Very frustrating. My buddy purchased one about the same time, and he fells the same about it. I wish it could be modified to make the "descend" position a larger area. ”
An innovative multifunctional descender developed to meet the demands of the most technical rope access and rescue specialists.
The patented internal mechanism combines with robust hot-forged construction and advanced ergonomics for exceptional control even with heavy loads (up to 210 kg for two person scenarios). In addition to its primary function as a descender, the Giant is also certified for use as a fall arrest device (i.e. during rope transfers), as an ascender with smooth upward glide, and as a belay device for climbing, making it the most widely certified rope tool of its kind. The actuating lever features an anti-panic system that locks the rope and arrests the descent in case of excessive pressure on the lever by the user as well as an extra lock off position so the worker does not have to tie off the device.
Belay device with assisted braking and anti-panic handle, for all single rope diameters (8.5 to 11 mm).
The GRIGRI + is an assisted braking device designed for all climbers, for both indoor and outdoor climbing. It can be used with all single ropes (optimized for 8.9 to 10.5 mm diameter ropes) and is suited for intensive use. The reduction handle offers exceptional descent control. Two usage modes to choose from, depending on need: top-rope belay or lead belay. The top-rope belay mode and the anti-panic handle make for a more comfortable belay, making the GRIGRI + particularly suitable for learning.
Self-braking descender with anti-panic function for work at height and rope access work.
The self-braking I'D S descender is designed for work at height and rope access work. It has an ergonomic handle that allows comfortable descent control. The integrated anti-panic function and anti-error catch limit the risk of an accident due to user error. The AUTO-LOCK system allows users to easily position themselves at a work station without having to manipulate the handle or tie off the device. Once locked, the rope can be taken up without having to manipulate the handle. The safety gate allows the rope to be installed with the device remaining connected to the harness. I'D S is compatible with 10 to 11.5 mm ropes and allows handling of loads up to 250 kg.
Self-braking descender with anti-panic function for technical rescue.
The I'D L self-braking descender is primarily designed for technical rescue. It has an ergonomic handle that allows comfortable descent control. The integrated anti-panic function and anti-error catch limit the risk of an accident due to user error. The AUTO-LOCK system allows users to position themselves without having to manipulate the handle or tie off the device. Once locked, the rope can be taken up without having to manipulate the handle. The safety gate allows the rope to be installed with the device remaining connected to the harness. I'D L is compatible with 12.5 to 13 mm ropes and allows handling of loads up to 280 kg.
These add-ons for the I'D give you additional options to manage our friction. The Open Brake may be used to increase the friction in accordance with the weight of the load and the diameter of the rope, or to release the rope at any time. The Closed Brake increases the friction as required for the load weight and rope diameter, and provides a constant redirect of the rope.

The RIG allows the user to move into position then easily stop where needed. This descender is compact and intuitive to use, making for smooth descents. A simple and effective alternative to more traditional descenders. The RIG’s handle allows the user to switch quickly between descent and stopping for work. While the handle is in descent position, it will automatically return to belay position if the user lets go of it. This limits risks in case of involuntary operation of the handle, for example by user action, a falling object, etc.
The RIG is better-adapted for professional use. Pivoting cam facilitates taking up the slack in the rope. Can also be used to make a reversible haul system, and for short ascents (in conjunction with a FOOTPRO foot loop and an ASCENSION handled rope clamp). Single ropes between 10.5 and 11.5 mm in diameter (7/16” ). This device is for users that already have considerable experience. For professionals that are still learning technical rope access skills, we recommend the Petzl I’D Descender, which has additional safety features, such as an anti-panic function and an anti-error safety cam. Weighs 400 grams. Instructions included.
Self-braking descender for work on ropes, which allows the operator to lower themselves on the working line, to position himself on the working line and to ascend the same rope. Equipped with a braking spur that creates additional friction on the rope, when used during the descent, without the use of an additional connector. A multi-functional command lever with an automatic recall system allows the operator to descend at a controlled speed and stop the descent at the desired point without the need to tie off the device. An EBS safety system (Extraordinary Braking System) is activated if the lever is accidentally fully opened, reducing the speed of descent instead of increasing it.
