This is a single hook rig with the opposite end of the leader not crimped. A proper size crimp is provided to form the loop end which will attach to the snap swivel of the main line once the squid is rigged.
Lay the hook and leader on top of the squid to get the length of the stop tubing with the rigging bead positioned as the rigging stop. Cut the blue stop tubing to length and slide on to the leader with the bead following.
When rigging, the leader is run up through the squid and out the tip. When the hook is set and the bead stop and tubing is positioned and the bait is sewn with floss the leader would then be crimped.
