Description

The Double Bight Figure Eight, also known as the 'Bunny Ears', is useful in climbing for equalizing two anchors and providing redundancy.

Strength/Reliability

Compared to many other double loop knots, the Double Bight Figure Eight is considered to be strong and secure, and it is fairly easy to adjust the size of the 'ears' or loops by moving rope from one of the loops to the other. Each loop shares a portion — roughly 50% — of the load. If either loop, either anchor, or either carabiner fails, the remaining anchor assembly should not be compromised.

Warning

Verify tying technique with a skilled instructor where knot failure could cause property damage, injury, or death.

Common Uses

  • create two separate loops in the middle of a rope.
  • attach a climbing rope to two different anchor points.
  • spread a load evenly between two attachment points.
  • make a double-loop tie-in for added safety.
  • rig a Y-hang from two anchor bolts in a cave.
