Z-clipping is a lead-climbing error where the climber accidentally pulls up rope from below the previous quickdraw to clip the next bolt, creating a ‘Z’ shape in the rope. It dramatically increases rope drag, can pull the climber off balance, and means the new clip provides little protection. The fix is to clip rope coming from above the last draw.
Why it happens
Usually when bolts are close together and you grab the wrong section of rope instead of the strand running up from your harness.
The fix
Trace the rope from your tie-in and clip that strand; if z-clipped, unclip and re-clip. Don’t confuse it with back-clipping — see back-clip vs z-clip on a lead.
Frequently asked questions
What is z-clipping?
Z-clipping happens when, instead of clipping the rope running up from your harness, you grab rope from below your previous quickdraw and clip it into the next one. This routes the rope in a 'Z', usually because the bolts are close together and you grab the wrong section.
Why is z-clipping a problem?
It creates severe rope drag that can stop you moving and pull you off balance, and the z-clipped draw gives almost no fall protection because the rope isn't running straight to your harness. It also wastes effort and can be alarming to discover mid-route.
How do you avoid z-clipping?
Always clip the rope coming directly up from your tie-in, tracing it with your eyes or hand from your harness if bolts are close together. If you realise you've z-clipped, unclip the offending draw and re-clip the correct strand.
