3.0 INSTALLATION
3.1 PLANNING: Plan your fall protection system before starting your work. Account for all factors that may affect your safety
before, during, and after a fall. Consider all requirements and limitations defi ned in Section 2.
IMPORTANT:
In most applications, the Nano-Lok SRL can be connected to the anchorage or the harness Dorsal
location. Either orientation is allowed; except as noted in Section 4.6.
3.2 ANCHORAGE: Figure 9 illustrates typical SRL anchorage connections. Select an anchorage location with minimal free fall and
swing fall hazards (see Section 2). Select a rigid anchorage point for each connection that is capable of sustaining the static
loads defi ned in Section 2.3. Where anchoring overhead is not feasible, Nano-Lok SRLs may be secured at dorsal D-Ring level
for 141 kg (310 lb) users (See Figure 3).
3.3 TIE-BACK ATTACHMENT: See Figure 9. Snap hooks and WrapBax hooks operate in the same manner. Grip the hook handle in
one hand. With your index fi nger, depress the locking mechanism in (A). With your thumb, pull back the gate latch (B). As the
gate latch is pulled back, the gate will open. Release your grip and the gate will close.
Wrap the tie-back portion of the lifeline (C) around an appropriate anchor (D), then open the gate of the Tie-back snap
hook and pass the lifeline through the hook. The blue lifeline may only be passed through the Tie-back hook once. Make
sure the Tie-back portion of the lifeline is captured and the gate closes completely.
CAUTION:
Do not tie-back onto the yellow SRL life line (E). Do not tie-back below the Dorsal D-Ring (F).
3.4 HARNESS MOUNTING: Some Nano-Lok SRL models include a Single Leg or Twin SRL Harness Interface for mounting the
SRL(s) on a Full Body Harness just below the Dorsal D-Ring (see Figure 7 and Figure 8 ):
Single SRL Harness Interface: Where worker mobility is critical, a Single SRL Harness Interface can be used to mount the
Nano-Lok SRL on the back of a Full Body Harness just below the Dorsal D-Ring (see Figure 7). The worker can then connect to
varied anchorage points located throughout the site with the Lanyard End of the SRL without repeatedly re-installing the SRL. To
mount the Nano-Lok SRL on a Full Body Harness with the Single SRL Harness Interface:
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 suffi cient space to slide the Single Leg Interface between the Web Straps and
Back Pad.
Open the Harness Interface: Push down on the Locking Buttons (C) simultaneously and slide the Locking Pin
(D) out.
2. Position the Harness Interface around the Web Straps: With the Locking Buttons (C) facing out and Gate
facing up, insert the Nose End of the Harness Interface (E) behind the Web Straps (A). Rotate the Harness
Interface behind the Web Straps until the Harness Interface surrounds the the Web Straps. Pull the Web Straps
back through the Dorsal D-Ring and Back Pad to secure the Harness Interface.
3. Attach the Nano-Lok SRL to the Harness Interface: Slide the Swivel Eye on the SRL (F) over the Harness
Interface's Locking Pin (D) and then push in the Locking Pin until it locks into place in the opposite end of the
Harness Interface.
WARNING:
Harness Interface is unlocked. To avoid accidental release of the connection, always make sure the Harness
Interface is locked before using the Harness and attached Nano-Lok SRL. Failure to do so could result in injury
or death.
NOTE:
It is also acceptable to connect the Nano-Lok SRL to the Harness Dorsal D-Ring with a Carabiner or
Snaphook.
• Twin SRL Harness Interface: In climbing applications where 100% tie-off is required, the Twin SRL Harness
Interface can be used to mount two Nano-Lok SRLs side-by-side on the back of a Full Body Harness just below
the Dorsal D-Ring (see Figure 8). To mount two Nano-Lok SRLs on a Full Body Harness with the Twin SRL Harness
Interface:
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 suffi cient space to slide the Twin Leg Interface between the Web Straps and
D-Ring Pad.
2. Open the Harness Interface: 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 fi rst Nano-Lok SRL onto the Harness Interface: 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 Harness Interface 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 SRL on the Harness Interface: 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 (I). Swing the Gate (E)
closed.
6. Close the Harness Interface: 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.
NOTE:
Older ExoFit harnesses may require a different Twin SRL Harness Interface. See Appendix A.
The Red Band on the knob end of the Harness Interface Locking Pin will be exposed if the
