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.

CONNECTING SYSTEM COMPONENTS: After fi tting the ExoFit NEX Harness the user may then connect to other system
components. Follow the guidelines in Section 2 and the manufacturer's instructions included with the component.

Unzip the Trauma Strap Pouch on each hip of the harness and deploy the Suspension Straps (Figure 12A).
2.
Raise the ends of the straps to access the hook and loops. Insert the hook into the loop that provides the desired
strap length.
3.
Lower the Suspension Strap and step onto the strap to alleviate pressure of the harness leg straps on the legs (Figure
