Pass the lower end of the loop through the upper

end and clip a carabiner into the lower loop. (You
can add more wraps if the knot slips.)

Garda Knot

A RATCHETING KNOT THAT EMPLOYS TWO
CARABINERS AND IS USEFUL IN HAULING

The Garda knot ratchets, allowing the rope to pass through

a pair of carabiners in one direction only. The two carabiners
should be the same size and shape, and they should not be

locking carabiners, since the locks prevent them from
pinching the rope firmly enough for the knot to work. This

knot might also be useful in camping. Note: If the rope rides
up onto the gates when the knot is in use, the Garda may

come unclipped. This can be prevented by maintaining
tension on the rope.
