USING THE ADJUSTERS: 3M Harnesses are equipped with a pair of adjusters for modifying the shoulder straps. See
Figure 9 for reference. See Figure 1 for which adjuster types are on your harness.

1. Tighten: Rotate the ratchet knob towards your body to tighten.
2. Loosen: Pull the ratchet knob out, then rotate the knob away from your body to loosen.

INSTALLING A HARNESS-MOUNTED SRD: Harness-mounted SRDs are secured directly to harnesses by means of a
harness interface. Harness interfaces are a type of connector specially designed for this purpose. In general, there are
two types of harness interface: straight-pin and carabiner. Instructions for each style are provided below.
;
Instructions may vary per harness interface model. For more information on how to use your harness interface, see
the manufacturer instructions for the harness interface or for the product it was provided with.
;
Do not remove the backplate from the harness when installing a harness-mounted SRD.
A. STRAIGHT-PIN INTERFACE: Straight-pin harness interfaces include a locking pin for securing to the harness.
Straight-pin interfaces may be used with Single-SRD or Twin-SRD formats, depending on the harness interface used.
See Figure 10A for reference.
1.
Press both Locking Buttons (A) on the front of your harness interface to open. With the Locking Buttons held
down, remove the Locking Pin (B) from the harness interface.
2.
Thread the Locking Pin (B) behind both Harness Straps (C), capturing the straps as you reinsert the pin into the
harness interface. An audible click should be heard when the Locking Pins are reengaged.
3.
Verify that the harness interface is secure and that both Harness Straps (C) are captured by the harness interface.
B. CARABINER INTERFACE: Carabiner interfaces are carabiners that function as harness interfaces. Carabiner
interfaces may be used with Single-SRD or Twin-SRD formats, although methods will vary slightly. See Figure 10B for
reference, which shows how to install the carabiner interface using a Twin-SRD format.
1.
Open the Gate (A) of the carabiner interface. Slide the SRD (C) over the open Arm (B) of the carabiner. Then,
slide the SRD to the opposite side of the carabiner.
2.
Hold the Gate (A) of the carabiner interface open, then slide the open Arm (B) behind and around both Harness
Straps (D), capturing the straps within the carabiner interface.
3.
Thread the second SRD (E) onto the open Arm (B) of the carabiner interface. Then, release the Gate to close and
secure the carabiner interface.
4.
Verify that the carabiner interface is secure and that both Harness Straps (D) are captured by the interface.
;
For Single-SRD formats, only one SRD should be attached to the carabiner interface. In this format, the
carabiner interface may be secured as outlined above, or directly to your Dorsal D-ring instead. If securing to your
Dorsal D-ring, do not capture the harness straps.
Certain harness models covered in these instructions include additional features for securing harness-mounted SRDs. See
below for how these features should be used:
•
SRD ADAPTER: Some harness models are equipped with an EZ-Link SRD Interface that integrates the dorsal D-Ring
with attachment elements for Harness-Mounted Self-Retracting Devices (SRDs). Figure 10C illustrates attachment of
common SRD configurations: (A) Nano-Lok™ Edge SRDs, (B) Twin Nano-Lok™ SRDs, (C) Single Nano-Lok™ SRDs, (D)
Rebel™ SRDs, and E) Twin Talon™ SRDs. See the manufacturer instructions for your SRD for more information.
;
Contact 3M Tech Services with any questions regarding compatibility of your SRD with the EZ-Link system.
