• Twin SRD Fixed D-Ring Harness Mounting: Older ExoFit Full Body Harnesses with a Fixed D-Ring require a
special SRD Harness Interface to mount two SRDs on the back of the harness just below the Dorsal D-Ring. To mount
two SRDs on an ExoFit Full Body Harness with the SRD Fixed D-Ring Harness Interface (Figure 10):
1. Loosen the Harness Webbing: Pull out on the Web Straps (A) where they pass through the bottom of the
Dorsal D-Ring (B) until there is sufficient space to insert the SRD Harness Interface between the Web Straps and
Back Pad.
2. Open the Harness Interface: With the SRD Harness Interface orientated as illustrated, push the Locking
Sleeve (C) to the right and then turn clockwise to unlock the Gate (D). Swing the Gate (D) down to open.
3. Thread the first SRD onto the Harness Interface: Insert the Nose of the Connector (E) through the Swivel
Eye (F) on the SRD and then rotate the SRD around to the Gate End of the Connector (G). The Gate can be
closed to allow clearance for the Swivel Eye between the Gate and Spine of the Connector.
4. Position the Harness Interface around the Web Straps: Insert the Nose of the Connector (E) behind the
Web Straps (A). Rotate the Connector behind the Web Straps until the Connector surrounds the Web Straps.
5. Add the second SRD on the Harness Interface: Slide the SRD's Swivel Eye (F) over the Nose of the
Connector (E) and position the SRD Swivel Eye in the Nose End of the Connector.
6. Close the Harness Interface: Allow the Gate (D) to swing closed and the Locking Sleeve (C) to rotate back to
locked position. Once the Harness Interface is closed, pull the Web Straps (A) back through the Dorsal D-Ring to
eliminate slack in the webbing and secure the Harness Interface between the Web Straps and Back Pad.

side-by-side on the back of a Full Body Harness just below the Dorsal D-Ring (see Figure 12). To mount two Nano-Lok
SRDs on a Full Body Harness with the Twin Carabiner:
1. Loosen the Harness Webbing: Pull out on the Web Straps (A) where they pass through the bottom of the
Dorsal D-Ring (B) until there is sufficient space to slide the Twin Leg Interface between the Web Straps and
D-Ring Pad.
2. Open the Twin Carabiner: Push up on the Connector Insert (C) to unsnap the Clamps (D) from the Connector
and then swing the Connector Insert up to unlock the Gate. Push the Gate (E) inward to open the Connector.
3. Thread the first Nano-Lok SRD onto the Twin Carabiner: Insert the nose of the Connector (F) through the
Swivel Eye (G) on the SRL and then rotate the SRL around to the Gate End of the Connector (H). The Gate can
be rotated toward the nose to allow clearance for the Swivel Eye between the Gate and Spine of the Connector.
4. Position the Twin Carabiner around the Web Straps: With the Gate facing up, insert the nose of the
Connector (F) behind the Web Straps (A). Rotate the Connector behind the Web Straps until the Connector
surrounds the the Web Straps.
5. Add the second Nano-Lok SRD on the Twin Carabiner: Slide the SRL's Swivel Eye (G) over the nose of the
Connector (F) and position the SRL Swivel Eye in the nose end of the Connector (F). Swing the Gate (E) closed.
6. Close the Twin Carabiner: Rotate the Connector Insert (C) forward so the Clamps (D) secure on the
Connector. When properly closed, the Web Straps should pass through the Webbing Slot (J) at the top of the
Connector Insert and the SRL Swivel Eyes should be secured in the Recesses (K) on either side of the Connector
Insert. Once the Harness Interface is closed, pull the Web Straps (A) back through the Dorsal D-Ring and D-Ring
Pad to eliminate slack in the webbing and secure the Connector between the Web Straps and D-Ring Pad.

Nano-Lok SRLs in climbing applications (see Figure 11) where 100% tie-off is required:
1. Loosen the Harness Webbing: Pull out on the Web Straps (A) where they pass through the bottom of the
Dorsal D-Ring (B) until there is sufficient space to slide the Twin Leg Interface between the Web Straps and
D-Ring Pad.
2. For single configuration: Place the swivel eye of a single SRL in the center open space.
3. For twin configuration: place the swivel eye of one SRL in the open space closest to the pin and one SRL in
the open space farthest from the pin.
4. Slide the pin back in place until you hear a click. The pin should be firmly locked in place.
5. Simultaneously depress the two buttons on the harness side of the connector while sliding the pin out. Sliding
this pin out creates on open space.
6. Pull up a small amount of slack in the webbing directly beneath the dorsal D-Ring on your harness. Place the
harness side of the connector beneath the D-Ring.
7. Slide the pin back in place ensuring that the pin remains beneath both layers of harness webbing until you hear
a click. The pin should be fi rmly locked in place.
4.0 OPERATION
;
First time or infrequent users of Self-Retracting Devices (SRDs) should review the "Safety Information" at the
beginning of this manual prior to use of the SRD.
4.1 BEFORE EACH USE: Before each use of this fall protection equipment carefully inspect it to assure it is in good working
condition. Check for worn or damaged parts. Ensure all bolts are present and secure. Check that the lifeline is retracting
properly by pulling out the line and allowing it to slowly retract. If there is any hesitation in retraction the unit should be
removed from service and destroyed. Inspect the lifeline for cuts, frays, burns, crushing and corrosion. Check locking
action by pulling sharply on the line. See the Inspection and Maintenance Log (Table 3) for inspection details. Do not use
if inspection reveals an unsafe condition.
4.2 AFTER A FALL: Any equipment which has been subjected to the forces of arresting a fall or exhibits damage consistent
with the effect of fall arrest forces as described in Table 3, must be removed from service immediately and destroyed.
