3.8 MAKING CONNECTIONS: When using a hook to connect to an anchorage or when coupling components of the system
together, ensure roll-out cannot occur. Roll-out occurs when interference between the hook and mating connector causes
the hook gate to unintentionally open and release. Self-locking snap hooks and carabiners should be used to reduce the
possibility of roll-out. Do not use hooks or connectors that will not completely close over the attachment object. See
subsystem manufacturer’s instructions for more information on making connections.
3.9 CONNECTING SYSTEM COMPONENTS: After fi tting the Pro 3 Harness the user may then connect to other system
