Square Lashing
Use this classic lashing to secure two spars that touch each other at the point where they cross. Begin the lashing with a clove hitch around the vertical spar, just below the crosspiece. Run the rope over the horizontal bar, around behind the vertical bar, then back over the face of the horizontal bar on the left. Tighten snugly, then bring the cord behind the vertical bar and up the right front side of the horizontal bar. Repeat this three or four times. Finish with two "frapping" turns to tighten the lashing, and lock everything in place with a clove hitch on the crosspiece.
