DMM Pinto Rig
Here's what other sites are saying:
Bring the DMM Pinto Pulley Rig along on your next gear-heavy, risk-intensive expedition. After all, it's fully strength-rated with a working load limit of 10kN and a breaking strength of 50kN. Since it accommodates ropes of up to 16mm in diameter, you don't have to worry about maxing out your safety margin with a beefy working-man's cord.
