Finger Jams

For cracks that are smaller than hand size, finger jams are the answer. You create finger jams by inserting some or all of your fingers into a crack, ideally to the second or third knuckle, and lock them off on a constriction in the crack or rotate your elbow down to torque your fingers into a jam. Think of a key going into a lock: You insert and twist.

Finger jams

To find the best finger jam you’ll need to experiment with placing different fingers in the crack. A crack that is too small to fit your index and middle finger might fit your pinkie and ring finger perfectly.

To get your index and middle finger into the crack try placing your fingers in with your hand in a thumb-down position. If the crack is too small to fit those fingers, turn your hand thumb up and insert your pinkie and ring finger. 

When a finger crack starts to get a little wider, try what’s called a ringlock to make a secure jam.

Ringlock technique:

  • Touch the tips of your thumb and index finger together to make an “OK” sign
  • Insert the finger-circle into the crack with your elbow up
  • Stack additional fingers on top of your index finger until you meet the width of the crack
  • Bring your elbow down to lock the jam into place

Finger crack climbing footwork

Finger-size cracks require fancy footwork. If the crack is wide enough, turn your foot so your big toe is up and try to get your toes in. You can also press your foot straight onto the crack and smear your foot on the edges of the crack, relying mostly on friction to create the foothold.

Remember to look for holds outside the crack; face holds can be essential to climbing up a finger crack.
