D-Ring Extenders have the potential to increase your Free-Fall Distance, affecting your
overall Fall Distance and may also increase the risk of Swing-Fall. Be sure that your Personal
Fall Arrest System (including this D-ring Extender) is rigged so as to limit your Free-Fall Distance
to 6 feet or less. Refer back to sections 2.8, 2.9 and 2.10 for additional details. If you have
questions about proper rigging, consult a competent person or your supervisor.
This product meets the requirements of OSHA 1926.502 as well as ANSI Z359.1-2007 and/or

3.2: Approved Applications
This D-Ring Extender is approved for Fall Arrest and Travel Restraint Applications where
easier access to the back d-ring of your Full Body Harness is required, provided that the
additional working length of your connection does not pose a hazard.
There are three basic types of D-Ring Extenders:
Snap hook with single d-ring: A double-locking snap hook connected to a single d-ring
or o-ring by a length of webbing.
Snap hook with loop: A length of webbing with a web-loop at one end, and a single d-
ring or o-ring at the opposite end.
Snap hook with 2 d-rings: A double-locking snap hook connected to a pair of d-rings or
o-rings by a length of webbing.
D-ring Extenders have additional uses. They can also be attached to an overhead anchorage
connector in order to provide an extension, making it easier to connect to.
D-ring Extenders may, in some cases, also be used as an anchorage connector. The snap
hook or web loop can be attached to a structural anchorage (such as structural rebar), provided
that the connection is compatible and will fully captivate the snap hook. See section 3.4 for
additional information on D-ring Extenders as anchorage connectors.
Also, be sure to consult Section 5 of this instruction manual for details on anchorage
considerations, as the anchorage and its relationship to the walking/working surface will be an
important factor in determining suitability and could contribute to the outcome of a fall event. Use
of an anchor point that is not properly rated could lead to a catastrophic failure of your personal
fall arrest system, which may result in serious injury or death.
3.3: Restricted Applications
D-ring Extenders must not be used in any application where the additional length may
increase the Free-Fall beyond the rating of your Shock-Absorbing Lanyard, Self-Retracting
Lifeline or Rope Grab (i.e. Rope Adjuster, Fall Arrestor or Rope Grab).
