Aztek Pulley System

A set of swivel blocks specifically designed for building a “Personal Mechanical advantage (AKA “Set of Fours”).

Ingenious design is super strong and allows wratchet Prusiks to be detached with a push button pin.

Each block has a built in swivel, and accepts 8-9mm rescue cord. Handy for those that find pulley systems confusing.

Comes with one pin, one becket cover and instructions.

Strength in position of function: 36kN
