b) 5,000 lbs. (22.2 kN) in the absence of certification.
3.5.2 Restraint Anchorage Strength: An anchorage selected for restraint applications must have a strength able to sustain a static load applied in the
direction permitted by the PFAS of at least:
a) Two times the maximum arrest force permitted when certification exists, or
b) 1,000 lbs. (4.4 kN) in the absence of certification.
3.6 Definitions: The following are definitions of terms.
Authorized Person: A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard (otherwise
referred to as "user" for the purpose of these instructions).
Certified Anchorage: An anchorage for fall arrest, positioning, restraint, or rescue systems that a qualified person certifies to be capable of supporting the
potential fall forces that could be encountered during a fall or that meet the criteria for a certified anchorage prescribed in this standard.
Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary,
hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
Qualified Person: A person with a recognized degree or professional certificate and with extensive knowledge, training, and experience in the fall
protection and rescue field who is capable of designing, analyzing, evaluating and specifying fall protection and rescue systems to the extent required by
this standard.
Rescuer: Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.
4. INSTALLATION AND OPERATION
Plan the installation of the anchor considering all facets of fall protection, anchorage location, fall clearance requirements, swing fall, and work zone.
Installation of anchorages must be under the supervision of a competent person trained in their design and use.
NOTE: Approved fall protection may be required during installation of all anchorage units discussed in this manual.
DO NOT use any anchorage discussed in this manual until the system has been completely installed, inspected, and approved for use by a competent person.
4.1 Anchorage Location: Select a suitable anchorage point that will support the strength requirement and minimize free fall and eliminate swing hazards.
The anchor is designed for use in window and door frames 21 inches to 51 inches wide.
4.1.1 Fall Arrest: For fall arrest applications, select an anchorage location that will facilitate maximum safety, minimize risk and be of sufficient strength to
meet requirements. See Section 3. Installation of the anchor must be under the supervision of a competent person. Do not work above the anchorage
location in any fall arrest application.
4.1.2 Restraint: For restraint applications, exercise caution in selecting an anchorage location. Ensure the anchorage meets strength requirements. See
Section 3. Under certain circumstances, it may be necessary to work above the anchorage (a foot‐level tie‐off) in a restraint application. Be aware of work
zone hazards and use caution under these circumstances. A fall with a foot‐level tie‐off may result in serious injury or death.
4.2 Fall Clearance Distance: When working at heights and using a PFAS, it is important to consider the distance between the walking/working surface and
the next lower level to ensure there is sufficient room for the PFAS to arrest a fall. Fall Clearance Distance is the distance that is required to safely arrest
the fall of a user. The Distance may be calculated by adding together the Length of the Lanyard or the SRD, plus the Deceleration Distance, the Height of
the Worker, plus a Safety Factor of 1‐1/2 feet. See Figures 1, 2, 3, 4 and 5 in Appendix B.
4.3 Swing Fall: Swing falls occur when the anchorage point is not directly above the point where a fall occurs. Swing falls are more prevalent when using
an SRD and a FACSS. In a swing fall, the total vertical fall distance will be greater than if the user had fallen directly below the anchorage point, thus
increasing the total free fall distance and the area required to safely arrest the user. Such swing fall injuries may be much more severe. Minimize swing
falls by working as directly below the anchorage point as possible. Move the anchorage as required. Never permit a swing fall if injury could occur. If a
swing fall situation exists in your application consult a competent person before proceeding. A minimum of six feet from the working level to the lower
level or nearest obstruction is recommended.
See Figure 3 in Appendix A.
DO NOT use the anchor for fall protection applications if the anchor will be installed below the level of the user's FBH D‐ring during normal work activities.
4.4 Anchorage Installation: Follow these steps;
1. Inspect the anchor before each use in accordance with the procedures listed in Section 7. Ensure the anchor is in good working order. If inspection
reveals damage of any kind or excessive wear, remove the unit from service immediately.
2. Determine a suitable location to install the anchor that will maintain a proper work zone. A proper work zone is limited to a 30 degree angle from the
D‐ring centerline, and up to 90 degrees below the D‐ring. See Figure 4 in Appendix A.
3. Loosen the final adjustment hand clamp as far as it goes. Remove the locking pin and slide the adjustment leg toward the fixed leg enough to fit in
the opening.
4. Place the anchor horizontally at the bottom of the opening. Place the fixed leg against one side of the opening. The adjustable leg may be on the left
or right. Ensure the anchor rests on the door or window sill. Ensure the D‐ring is facing the fall hazard as shown in Figure 5 in Appendix A
5. Slide the adjustable clamping leg as close as possible to the door or window jamb.
6. Insert the locking pin into the holes that provide the best preliminary fit. Secure the locking pin with the hair spring pin. See Figures 6A and 6B in Appendix A.
7. Tighten the final adjustment clamp hand tight against the door or window jamb.
Ensure the horizontal body is butted securely against the frame of the opening.
Ensure the fixed leg and the adjustable leg are butted securely against the frame of the opening.
Ensure the anchor is as low as possible in the opening. Failure to comply with this instruction could lead to an unintentional disengagement if a fall
8. Attach the PFAS to the anchorage D‐ring. Consult the PFAS manufacturer's user instructions for complete details. Make only compatible connections.
NOTE: Do not go back through the opening the anchor is installed in to perform work. A fall event in this area this will cause a reverse load and may
unintentionally dislodge the anchor.
DO NOT place the anchor vertically in the opening.
DO NOT over tighten the hand clamp.
DO NOT drop the anchor from roof‐tops to the ground.
DO NOT subject the anchor to non‐design loads or forces.
DO NOT exceed the proper load direction.

occurs, resulting in injury or death.
