CONNECTING TO ANCHORAGE:
Figure 7 illustrates typical SRD anchorage connections. Select an anchorage (A)
capable of sustaining the static loads defined in Table 1. The SRD must be mounted on the user’s full body harness.
A. HARNESS MOUNTING:
Harness-mounted SRDs are secured to the full body harness directly by their Harness
Interface (C). The user then secures to anchorage connection points using their Bottom Connectors (B). Twin-SRD
models enable the user to maintain 100-percent tie-off when transferring between anchorage points.
;
Large-throat snap hooks must never be secured to D-rings or other connecting elements unless they have a
gate strength of 16 kN (3,600 lbf) or greater.

INSTALLING A HARNESS-MOUNTED SELF-RETRACTING DEVICE:
Single- and Twin-SRD models with harness web
interfaces as their top connector may be installed directly onto the user’s full body harness. This format enables easier
transportation of the SRD and ensures that the SRD is within reach when moving between anchorage points. The methods
for mounting an SRD on a harness vary with SRD model and the interface provided.
;
Harness interfaces may also be used in coordination with specific features of full body harnesses to secure the
Single- or Twin-SRD to the harness. Examples include the pSRD Link and the molded X100 SRD Interface Loop present
on some 3M harness models. The following instructions provide a general method for how each harness interface
should be used. See the manufacturer instructions of your full body harness for more information on specific features
for interfacing with SRDs.
A. NANO-LOK EDGE SRD INTERFACE:
See Figure 8 for reference. These instructions apply to the Nano-Lok Edge
SRD, which includes an integral SRD interface for mounting on a harness.
1.
Loosen the harness webbing. Pull out on both Shoulder Straps (A) where they pass through the bottom of the
Dorsal D-Ring (B) until there is sufficient space to slide the locking pin between the Shoulder Straps and Back
Pad.
2.
Open the harness interface. Push down on the Locking Buttons (C) simultaneously and slide the Locking Pin (D)
out.
;
Both locking pins must be fully depressed to allow the locking pin to slide out. To slide the locking pin
open, apply firm pressure to both locking buttons with the thumbs while simultaneously pulling on the locking
pin head with an index finger.
3.
Insert the locking pin through the shoulder straps. With the Locking Buttons (C) facing out and locking pin facing
up, insert the Detent Pin (D) of the Harness Interface (E) behind both Shoulder Straps (A) and lock in place. Pull
the shoulder straps back through the dorsal D-ring and back pad to remove slack.
4.
Connect hook and loop straps around the shoulder straps. Open the Hook and Loop Straps (F) located on the
bottom of the energy absorber pack. Wrap the hook and loop straps around the shoulder straps and secure.
;
The red band (G) on the knob end of the locking pin will be exposed if the harness interface is unlocked.
To avoid accidental release, always make sure the harness interface is locked before using the harness and
attached SRD. Failure to do so could result in injury or death.
