A good rule of thumb in climbing is to never let anything hang below your knees. But what do you do with that "alpine quickdraw" of a single (2 foot) or double (4 foot) runner to shorten it up for racking?
A simple trick is this method, best described with a photo. This triples up the webbing material, shortening your quick draw. You can clip it doubled like this, or remove two of the three strands from one carabiner to use it at full extension.
(I learned this crafty trick decades ago, and still remember my joy and fascination at seeing it for the first time. For some reason I thought it was the most clever thing ever, and hopefully if this is new to you, you think somewhat the same thing. :-)
1 - Start with a runner and two biners.
2 - Pass one biner through the other.
3 - Clip the bottom loop.
Done! A short and compact draw that hangs nicely on your harness, but is easy to deploy at full length.
