SAR A-B Descender

The A-B Descender conforms to two standards EN12841-C as a Rope Adjustment device (Descender) and EN341-C Descenders for Rescue. The two standards are very different. EN12841-C covers the device only, so that it can be used different types of Kernmantle rope, in accordance with the SAR user instructions. EN341 is the standard for a decent rescue/egress system and any system conforming to this standard must be used with the rope with which it was tested.
Over the past ten years the EN12841 standard has been adjusted to suit the requirements of the users. Testing cannot be done on all rope types, diameters and conditioning as this could take years and the cost be too restrictive, so the user has to understand that each rope used in the device with this standard will give a different reading in test’s or feel in use.

Some of the problems with other descenders are creep, too sensitive, panic brakes too slow or fast to activate, unable to pull rope through easily or not at all and over complicated design. With the A-B Descender we hoped to have overcome all these with the simplicity of its design. The A-B Descender has had some design changes from suggestions of users of the old SCARAB. A spring has been added to help keep the handle close to the body when not in use, a small bobbin as a rope keeper and the main change is a flip down handle to give extra leverage when required and a finer control in descent.

NOTE: All friction brakes create heat which can damage rope if a fall has taken place or on a long fast descent. Any strength quoted is when the product is new and is in accordance with the appropriate standards.


The A-B Descender has been tested by the notified body in a simulated rescue using a 210kg mass as required in 12841-C 4.4.5 and 4.4.9. It has also been tested with 100kg loaded on the descender and 100kg on a one meter wire sling in a fall factor one scenario which is a more realistic test. Maximum impact force recorded was 5.7kN, max slip on rope was 15cm and there was only slight glazing to the rope. There was no damage to rope or descender. SAR confirms it can be used in RESCUE with a two person load. The A-B Descender also conforms to EN341-C for 20 x 100M descents with 100kg mass using SAR 16 plait 11mm low stretch rope. 12841-C is a far higher standard than EN341, the number of descents and distance is irrelevant. In EN12841-C you can descend as many times as required and at whatever distance. The only ruling factor in this standard is degradation on the descender and rope.


  • Colour: BLACK
  • Rope: 10.5mm to 12.5mm Kernmantle
  • Max Load: 300kg
  • Control: Leaver/Cam + Panic Grab Brake.

SAR has once again had to alter the name of the descender from SCARAB to SARAB and now to the A-B Descender. We are extremely sorry for the inconvenience caused to our customers over this problem, but in the end what’s a name between friends.

We hope you will be completely satisfied with every purchase made from Abaris International Ltd as we strive to offer you excellent quality, value and service at all times. Whilst we try to be as flexible as possible with returns, we have to be aware of the safety critical nature of many of our products, and the need for us to guarantee the safety, quality, maintenance and storage of these products.


In line with all other professional suppliers of Personal Protective Equipment / Personal Fall Protection Equipment and for the safety of all our customers, we are ordinarily unable to exchange or issue a refund for any personal safety equipment such as ropes, harnesses, helmets, descenders, ascenders, karabiners etc once the items have left our premises, or in the case of orders sent out by post / courier, received by a customer. This does not apply to any item which has arrived faulty or damaged, or if the item has been dispatched as ordered, but is unwanted due to the description on the website being incorrect or misleading.

If we have sent you the wrong item please contact us as soon as possible (latest within 24 hours of receipt of your order), and subject to the time of day we are made aware of our error, we will endeavour to send the correct item out to you the same day, and arrange delivery of that item and collection of the wrong item the next day (slightly longer for Highlands and Islands and overseas). The item needs to be in its original and undamaged packaging and with its tags / labels still attached. We will not be able to accept return of any product that does not meet these criteria.

In certain other limited circumstances we may be willing to offer an exchange or refund, but need to be notified within 24 hours of you receiving the goods and require the product to be in exactly the same condition that it left us i.e. in its original and undamaged packaging and with the tags / labels still attached. If the tags / labels have been removed then the item is not returnable under any circumstances. Any goods accepted back for any other reason than we have made an error or the item is faulty, will be subject to a 15% inspection / re-certification fee, as we are required to complete a full PPE inspection on the item before it can be deemed suitable for resale, even when an item is returned to us unused and has seemingly not been removed from its packaging. Once the item has passed the formal inspection we will refund the cost of the goods minus the 15% inspection / recertification fee. Goods must be returned to us at your own expense and must be adequately packaged to protect against damage.
