chinook Posted June 27, 2005 Share Posted June 27, 2005 In the day we always used 1 inch for rap slings. I've been seeing 9/16 on alpine routes and would like to hear some comments... Quote Link to comment Share on other sites More sharing options...
selkirk Posted June 27, 2005 Share Posted June 27, 2005 Is it climb spec or mil spec 9/16? Not that it should matter for 1 rap. Don't think i'd trust the mil spec 9/16, without a rap ring for more than 1 rap though. Stuff is pretty thin and it seems rope/sling friction would probably weakn it significantly, though the climb-spec should be fine for as long at 1 inch mil-spec.

forrest_m Posted June 27, 2005 Share Posted June 27, 2005 9/16 & 1/2 inch rap sling weighs less, is less bulky and is more flexible when it comes to rapping off of jammed knots and similar trickery. it's certainly plenty strong enough for the forces that rapelling puts on it. Â i imagine that 1" webbing is more durable on routes that see a lot of traffic, but to be honest, when i'm setting raps, i'm usually not too worried about subsequent parties. it's always a judgement call whether you are going to trust in situ rap slings, no different with thinner slings.

chinook Posted June 27, 2005 Author Share Posted June 27, 2005 Let's assume climb spec, water knot and a ring. Quote Link to comment Share on other sites More sharing options...
Dru Posted June 27, 2005 Share Posted June 27, 2005 9/16 and 1/2 fits better through abalakovs too Quote Link to comment Share on other sites More sharing options...
selkirk Posted June 27, 2005 Share Posted June 27, 2005 Let's assume climb spec, water knot and a ring. Â Effecitvely just as strong as 1" mil-spec. Should be good for 2 or 3 seasons maybe? Or at least until the snaffles and sunlight degrade it to sketchiness. Quote Link to comment Share on other sites More sharing options...
Ireneo_Funes Posted June 27, 2005 Share Posted June 27, 2005 I bailed off a route last week using 1/2" webbing and a rap ring. It worked just fine. Quote Link to comment Share on other sites More sharing options...

catbirdseat Posted June 27, 2005 Share Posted June 27, 2005 In the day we always used 1 inch for rap slings. I've been seeing 9/16 on alpine routes and would like to hear some comments... 9/16 is fine with or without rap rings. Some of my runners are sewn spectra but I always carry some tied 9/16 climb spec nylon runners for rappels, when necessary. Quote Link to comment Share on other sites More sharing options...
Bill_Simpkins Posted June 27, 2005 Share Posted June 27, 2005 (edited) I've had 9/16 mil spec almost compleltly severe do to rubbing and sharp edges after one use. This was used on make-shift aiders and hook ties. I avoid using it except for utility purposes. I've rapped off the stuff through a bolt when retreating(wimping out) on a route before, but I wouldn't use it around a tree or rock as friction and pressure may severe it, even on one use. I think the climbing spec is ok for whatever. Edited June 27, 2005 by Bill_Simpkins Quote Link to comment Share on other sites More sharing options...
