FallTech 83663 - Manual (Page 11)

D-ring Extenders must not be used in any application where they will increase your fall
distance enough to exceed the Clear-Fall requirements of your Personal Fall Arrest System.
D-ring Extenders are rated only for single users, with a maximum capacity of 310 lbs. Never
attempt to attach multiple users to a D-ring Extender under any circumstances.
3.4: Installation and Use – Full Body Harness
D-ring Extenders must only be attached to the back d-ring of your Full Body Harness. Never
attempt to connect a D-ring Extender to a front, side or hip d-ring under any circumstances.
1. For D-ring extenders having a snap hook at the attachment end, attach this snap hook to
the back d-ring of your full body harness and ensure that the gate closes and latches
automatically. For web loop versions, pass the web loop through the back d-ring of your
full body harness and then pass the d-ring or d-rings through the loop and choke the
Extender down around the back d-ring of your FBH.
2. Proceed to your work location and tie-off using your preferred connecting device (Shock-
Absorbing Lanyard or Self-Retracting Lifeline) by fastening the attachment-end connector
to the d-ring at the end of your extender. Be sure that you are using your Shock-
Absorbing Lanyard or Self-Retracting Lifeline in accordance with the manufacturer’s
instructions.
3. If you are using a twin d-ring style D-ring Extender, you may have a Shock-Absorbing
Lanyard attached to one of the two d-rings, leaving the other d-ring available for
attachment to a Self-Retracting Lifeline. In this configuration, if you are tied-off to the
Self-Retracting Lifeline, be sure that the anchorage-end connector or connectors on your
Shock Absorbing Lanyard are attached to the lanyard keepers or lanyard parking
locations on your Full Body Harness.
4. Do not attempt to connect more than one connector (i.e. snap hook or carabiner) to the
back d-ring of your Full Body Harness – this is an incompatible connection. If you need
to make multiple connections to your back d-ring, you may use two web loop style D-ring
Extenders (i.e. model # 7366L / 8366L) or you may select and twin d-ring style (i.e. model
# 7366TD / 8366TD or 73662D / 83662D).
5. Do not attempt to connect more than one device to the d-ring or o-ring on your D-ring
Extender. If you are using or transitioning between multiple devices, be sure to use a
twin d-ring style D-ring Extender (i.e. 8366TD or 83662D).
Once the above steps have been taken, the user will have access to their work area while
walking and moving at normal speeds. It is important not to make sudden or dramatic
movements! When using this device, care must be taken to be aware of the work environment
and any hazards, obstructions or obstacles that may exist. Be careful of any and all fall hazards
and also be aware of slipping and tripping hazards as well.
3.5: Installation and Use – Anchorage Connector Extension
In the event that you are utilizing an overhead-mounted anchorage connector (i.e. a beam
anchor mounted 10 feet above the walking working surface), a D-ring Extender may be used to
grant easier access to your anchorage. Model numbers 7366TD / 8366TD, 73662D / 83662D
and 7366L / 8366L may not be used in this application.
1. Ensure that the connection point (d-ring, o-ring or formed eye) on your anchorage
connector is compatible with the hook on your D-ring Extender. Also ensure that the D-
ring Extender will not be exposed to sharp/abrasive edges or any other object or
obstruction that could cause damage or force a disengagement in the event of a fall.
