•  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 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.

Twin Pin Carabiner:

 This harness attachement can be used to mount one Nano-Lok SRL, or two 

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 firmly 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:

 Verify that your work area and Personal Fall Arrest System (PFAS) meet all criteria defined 

in Section 2. Verify that a formal Rescue is in place. Inspect the SRD per the ‘User’ inspection points defined in the 

“Inspection and Maintenance Log” (Table 2). If inspection reveals an unsafe or defective condition, remove the system 

from service immediately. See Section 5 for more information. 

4.2  AFTER A FALL:

 If the SRD is subjected to the forces of arresting a fall or exhibits damage consistent with the effect of 

fall arrest forces as described in Table 3, it must be removed from service immediately. Clearly mark the SRD “DO NOT 

USE” and then either destroy the device or contact 3M regarding replacement. See Section 5 and 6 for more information.

4.3  BODY SUPPORT:

 A full body harness must be worn when using SRDs. For general fall protection use, connect to the 

back (dorsal) D-ring.

4.4  MAKING CONNECTIONS:

 Figure 12 illustrates harness and anchorage connections for SRD Fall Arrest Systems. When 

using a hook to make a connection, ensure roll-out cannot occur (see Figure 5). Do not use hooks or connectors that 

will not completely close over the attachment object. Do not use non-locking snap hooks. The anchorage must meet 

the anchorage strength requirements stated in Table 1. Follow the manufacturer instructions supplied with each system 

component.

4.5 OPERATION:

 Prior to use, inspect the SRD as described in Table 3. Figure 12 shows system connections for typical 

SRD applications. Connect the SRD to a suitable anchorage or mount the SRD on the back of a Full Body Harness per the 

instructions in Section 3. On anchorage connected SRDs, connect the Hook (D) or Carabiner on the Load Indicator to the 

Dorsal D-Ring (A) on the Full Body Harness. On harness mounted SRDs, connect the Hook (D) or Carabiner to a suitable 

anchorage. Ensure connections are compatible in size, shape, and strength. Ensure hooks are fully closed and locked. 

Once attached, the worker is free to move about within the recommended working area at normal speeds. If a fall occurs 

the SRD will lock and arrest the fall. Upon rescue, remove the SRD from use. When working with an SRD, always allow 

the lifeline to recoil back into the device under control.

4.6  TWIN SRD INTERFACE 100% TIE-OFF:

 When two SRDs are mounted side-by-side on the back of a Full Body 

Harness, the SRD Fall Arrest System can be used for continuous fall protection (100 % tie-off) while ascending, 

descending, or moving laterally (see Figure 13). With the Lanyard Leg of one SRD attached to an anchorage point, the 

worker can move to a new location, attach the unused Lanyard Leg of the other SRD to another anchorage point, and 

then disconnect from the original anchorage point. The sequence is repeated until the worker reaches the desired location.
