4.5 WRAPBAX™ ATTACHMENT: WrapBax snap hooks operate in the same manner as many conventional snap hooks.
See Figure 11-D: Gripping the hook in one hand, the index fi nger depresses the locking mechanism (E). With the thumb,
the gate latch is pulled back (F). As the gate latch is pulled back, the gate will open. Release the grip and the gate will
close. Wrap the WrapBax portion of the lifeline around an appropriate anchor (G), then open the gate of the WrapBax
snap hook and pass the WrapBax web portion of the lifeline through the snap hook. The lifeline may only pass through the
WrapBax hook once. Make sure the Wrapbax portion of the lifeline is captured and the gate closes completely.
Only the WrapBax hook may be used to snap back onto the WrapBax portion of the SRD Lifeline. When
installed, the WrapBax hook must contact the heavy web section (WrapBax portion of the lifeline). If the anchor
structure is so large that the WrapBax hook contacts the lifeline above the WrapBax portion of the lifeline,
a different anchor structure must be used. Failure to heed this warning may result in equipment malfunction,
serious injury, or death.
A minimum setback distance of .9 m (3 ft) is required when using Nano-Lok Edge SRDs incorporating a
WrapBax attachment.
Never connect the WrapBax snap hook of one SRD to the lifeline of another SRD or lanyard. Failure to heed
this warning may result in equipment malfunction, serious injury or death.
4.6 OPERATION: Prior to use, inspect the SRD as described in Section 2.2 and the schedule in Table 2. Figure 11 shows
system connections for typical SRD applications. Connect the SRD on the back of a Full Body Harness per the instructions
in Section 3. 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.
4.7 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 11B). 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. Considerations for
Twin SRD 100% tie-off applications include the following:
• Never connect both SRD Lanyards to the same anchorage point. (See fi gure 12a)
• Connecting more than one connector into a single anchorage (ring or eye) can jeopardize compatibility of the
connection due to interaction between connectors and is not recommended.
• Connect each SRD Lanyard to a separate anchorage point. (See fi gure 12b)
• Each connection location must independently support 2,248 lbs (10 kN) or be an engineered system, as with a
Horizontal Lifeline.
• Never connect more than one person at a time to the Twin SRD system. (See fi gure 12c)
• Do not allow the Lanyards to become tangled or twisted together as this may prevent them from retracting.
• Do not allow any lanyard to pass under arms or between legs during use.
4.8 HORIZONTAL SYSTEMS: In applications where the SRD is used in conjunction with a horizontal system (i.e. Horizontal
Lifeline, Horizontal I-Beams Trolley), the SRD and horizontal system components must be compatible. Horizontal systems
must be designed and installed under the supervision of a qualifi ed engineer. Consult the horizontal system equipment
manufacturer's instructions for details.
5.0 Inspection
5.1 RFID TAG: The Self-Retracting Device includes a Radio Frequency Identifi cation Device (RFID) tag (see Figure 13). The
RFID tag can be used with the handheld reading device and web based portal to simplify inspection and inventory control
and provide records for your fall protection equipment. For details, contact a 3M Customer Service representative (see
back cover). Follow the instructions provided with your handheld reader, or on the web portal, to transfer your data to
your web log.
5.2 INSPECTION FREQUENCY: The Self-Retracting Device must be inspected at the intervals defi ned in Section 2.
Inspection procedures are described in the "Inspection & Maintenance Log" (Table 3).
Extreme working conditions (harsh environments, prolonged use, etc.) may require increasing the frequency of
inspections (see Table 2).
5.2 UNSAFE OR DEFECTIVE CONDITIONS: If inspection reveals an unsafe or defective condition, remove the SRD from
service immediately and discard (see Section 6).
Only 3M or parties authorized in writing may make repairs to this equipment.
5.3 PRODUCT LIFE: The functional life of 3M Self-Retracting Devices is determined by work conditions and maintenance. As
long as the product passes inspection criteria, it may remain in service.
