3.0 INSTALLATION
3.1 PLANNING: Plan your Fall Protection system before installation. Account for all factors that may affect your safety
before, during, and after a fall. Consider all requirements, limitations, and specifications defined in these instructions.
Additionally, the following points should be considered when planning your system:
• Anchorage: Select an anchorage capable of sustaining the Static Load requirements of the intended Fall Protection
application. See the manufacturer instructions for each component of your Fall Protection system for more
information. The anchorage location should address all limitations described in these instructions.
• Sharp Edges: Avoid working where system components may be in contact with, or scrape against, unprotected
sharp edges and abrasive surfaces.
• After a Fall: If the Full Body Harness is subjected to fall arrest or impact force, remove the Full Body Harness from
service immediately. Clearly tag the system “DO NOT USE”. See Section 5 for more information.
3.2 FASTENING BUCKLES: 3M Harnesses are equipped with a variety of Buckles for fastening and adjusting Leg Straps and
Chest Straps. See Figure 1 for the buckle types present on your Delta Harness. Figure 9 illustrates operation of each of
the following buckles:
1. Quick Connect Buckles:
A. To fasten the Quick Connect Buckle: Insert the Tab into the Receptor until a click is heard.
B. To adjust the attached Web Strap: Pull the Web Strap forward or backward through the Buckle Slot to tighten
or loosen.
C. To release the Quick Connect Buckle: Squeeze the Lock Levers on either side of the Receptor. Pull the Tab out
of the Receptor.
2. Pass-Through Buckles:
A. Insert the Male Buckle through the slot in the Female Buckle.
B.
Tighten the free strap so that the Male Buckle is flush against the Female Buckle. Secure the free strap in the
Strap Keeper.
3.3 HARNESS ADJUSTMENTS: Delta Harnesses are equipped with a pair of Torso Adjusters for adjusting the Shoulder
Straps. Figure 10 illustrates operation of the Torso Adjusters:
1. Pull-Thru Adjusters: To adjust Shoulder Straps with Pull-Thru Adjusters:
A. Tightening: Pul on the loose web end as illustrated in Figure 10 to tighten the Shoulder Strap.
B. Loosening: Rotate the buckle as illustrated in Figure 10 to loosen the Shoulder Straps.
2. Spring Adjusters: To adjust the Shoulder Straps with Spring Adjusters:
A. Tightening: Pulling the free end of the webbing straight out away from the buckle as illustrated in Figure 10 will
increase the tension on the strap.
B. Loosening: Tension can be released by pulling the adjuster tab and allowing the webbing to slip through the
buckle.

Procedures for buckling and adjusting the straps on your Delta Harness will vary with the harness model. See
Sections 3.2 and 3.3 for more information, as well as Figures 9 and 10.
1. Lift up and hold the harness by its Dorsal D-Ring. Prevent any harness straps from twisting through the following
steps.
2. Grasp the Shoulder Straps and slip the harness onto one arm. The Dorsal D-Ring should be placed on your back.
Ensure that the harness straps are not tangled and that they hang freely. Slip your free arm into the harness and
position the Shoulder Straps on top of your shoulders. The Chest Strap and Chest Buckle will be positioned on your
front when worn properly.
3. Reach between your legs and grasp the Leg Strap on your right side. Bring the strap up between your legs and
connect it to the mating buckle on your right hip. Adjust the Leg Strap for a snug, comfortable fit. When comfortably
adjusted, tuck the loose end of the Leg Strap under the Strap Keeper.
Repeat this process to buckle and adjust the left Leg Strap.
4. If present, adjust and fasten the Tongue Buckle Waist Belt.
5. Fasten and adjust the Chest Strap. The Chest Strap should be 6.0 in. (152 mm) down from the top of your shoulders.
When comfortably adjusted, tuck the loose end of the Chest Strap under the Strap Keeper.
6. Adjust the Shoulder Straps for a snug, comfortable fit with the Torso Adjusters. Each Shoulder Strap should be
adjusted to the same length. The Chest Strap should be centered across your lower chest, approximately 6.0 in. (152
mm) down from your shoulders. The Dorsal D-Ring should be centered between your Shoulder Blades. The Sternal
D-Ring, if present, should be located laterally within 2.0 in. (51 mm) of the vertical centerline of the harness.
