miladugga Posted November 2, 2006 Share Posted November 2, 2006 Hey all, I've started using an autoblock to rappel, (prusik cord around the rope to a leg loop with locking biner)especially if I am cleaning gear on the way down. My question is, is this safe? I'm thinking about how hot an atc gets rapping, and how they say not to run a weighted rope through a sling. Am I weakening the cord this way? So far they look and feel OK... Quote Link to comment Share on other sites More sharing options...
Farrgo Posted November 2, 2006 Share Posted November 2, 2006 I wouldn't recommend nabing your autoblock sling for the last piece before an epic runout. Probably best that this one gets left just for an autoblock or racking gear. I have a couple slings dedicated to just such a purpose. Also, consider using cord instead of a expensive sling for your autoblock. It will work just as well and you can cut it for the correct weight. Mtn. Freak was showing me how he cuts the cord and then keeps it on his leg loop so its ready when its time to rappel. Quote Link to comment Share on other sites More sharing options...
Dr_Flush_Amazing Posted November 2, 2006 Share Posted November 2, 2006 RC.com article on autoblocks As long as you keep the autoblock cord pretty loose on the rope, it shouldn't generate much friction+heat. Definitely check the cord periodically (after every rappel wouldn't be too much) for abrasion+melting. I would recommend not relying on the autoblock cord 100% to hold you. If you need to stop while rappelling to clean gear, mess with ropes, etc., take the time to wrap the brake hand end of the rope around your thigh a few times. That and your autoblock will insure that you aren't going to go anywhere.
