You'd use a stop only as the lower of the two ascenders assuming there is noone below you (ie rope not in tension.). There would probably be better alternatives to hand anyway. By far my favourite is a 4ft sling and an HMS karabiner. Clip the sling in to the karabiner and then wrap around the back of the karabiner and the rope, winding upwards. Clip into the free end. Much better than a prussikk (sp?). ...d |

Much better than a prussikk (sp?). there is nifty little thing Petzl have just brought out, basically just one of the spiky ratchet thingies from a croll that clips to a krab and makes an instant prusic (sp?) ideally you would have two buy you could manage with one if you moved a fig8/Stop up below it. Only a few quid and an essential bit of emergency kit if you don't have a full SRT rig. |

Only a few quid and an essential bit of emergency kit if you don't have a full SRT rig. Extra weight and no use for anything else.. It is perfectly possible to use a normal climbing rack to do SRT, just takes a bit more ingenuity.. As it is perfectly possible to abseil without a specific abseil device. It is always useful to be able to 'make do' with what kit you have. ...d |

Sorry, I'm a caver not a climber, what is a climbing rack? (presumably nothing like a descending rack) As it is perfectly possible to abseil without a specific abseil device. again the only thing which springs to mind is an Italian hitch (not recommended) what other methods are there? BTW I am all in favour of improvising because e.g. incidents on non SRT trips are exactly where you may have to. |

That is the one ;-) Or the faster version where you dont bother with the crotch but wrap the rope around your arms and wear a hole in the jacket. Of course, I see your point. My experience of climbing and abseiling is 25 years out of date! I presume you mean that a "descender" may be modified to use as an "ascender"? What about a rack? Climbing rack = full set of gear. caving rack = descender with multiple bars (can be approximated using about 3 dozen karabiners.) In man cases though it is easier to just make do with ordinary kit (sling and karabiner, or just sling) instead. The prussik knot is however a work of stan and shouldn't be used. ...d -- MatSav |

![]() "MartinM" wrote Sorry, I'm a caver not a climber, what is a climbing rack? (presumably nothing like a descending rack) Collection of carabiners, hexes, stoppers, camming devices, slings, etc., carried by a climber to set anchors and place protection while climbing. Varies from climber to climber and from climb to climb. As it is perfectly possible to abseil without a specific abseil device. again the only thing which springs to mind is an Italian hitch (not recommended) what other methods are there? Dulfersitz: Straddle the ropes, bring the rope up and over one's shoulder from behind, then across the front of the torso and down past the opposite hip. Painful, not recommended, only works on low angle terrain, only done in the direst of emergencies. I tried this once on a very short rappel, we were descending from a long route in Yosemite Valley after bivying on the summit of Sentinel Rock and my partner thought it would be faster than unpacking the harnesses. Never again. Foot brake: Rope is passed under the sole of one foot and over the instep of the other foot, climber stands very upright and lowers himself with his hands. I watched a free-soloist do this on the backside of one of the Boulder Flatirons on my rope after my partner and I had descended. Neither I or my partner had any interest in trying this novel technique ourselves. 2 carabiner brake: two carabiners laid end to end with enough overlap to pass the ropes through. Rope is woven through the two overlapping carabiners as it would be through a descending rack. This is best done with the funny banana shaped locking carabiners that used to be favored by Czech and other east European climbers. In fact, I first saw this done by a Czech climber who proudly told me that this was "East European Technique". 4 carabiner brake: 2 carabiners are stacked on top of one another w/ gates opposed and reversed. A bight of rope is fed through these carabiners, then 2 more are clipped across the first two to form a brake bar, as in a descending rack. With enough carabiners, one can build as long a descending rack as one wishes. Works best w/ oval carabiners. Very effective, very dependable, every climber should know this technique. -- mark BTW I am all in favour of improvising because e.g. incidents on non SRT trips are exactly where you may have to. |

Been down all sorts of terrain in the Lakes, Scotland, Wales and Alps that way. Bowline and two half hitches round the waist to tie on too.
