1. DESCRIPTION
The FallTech® Ring Plate Anchor covered in this manual is designed to provide a fall protection anchorage for persons working at height on wood
structures and subject to fall hazards.
The anchor is intended for use by construction and maintenance personnel on residential and commercial roofs, and other locations where fall
hazards exist.
This manual contains two appendices, Appendix A and Appendix B. Appendix A contains tables and figures specific to the anchor. Appendix B contains
tables and figures for fall protection in general. All figure, table, and chart references in this manual are to Appendix A unless otherwise noted.
For purposes of this manual, the anchor, in all iterations, may be referred to collectively as the Ring Plate Anchor, the anchor, the equipment, the
device, the product, or the unit.
The anchor is designed to be temporary and reusable, provided it has not been subjected to fall arrest forces and passes inspection as described in
Section 7 of this manual.
The anchor may also be used as a restraint anchor depending upon the workplace geometry and the available restraint system components.
The anchor is composed of a steel attachment ring, secured by a V-bracket welded to a steel base plate. The base plate has three holes to mount
the anchor to a wooden structure with lag screws in predrilled holes. See Figure 1 and Table 1.
1.1 Occupational Safety and Health Act (OSHA): The anchor discussed in this manual meets OSHA 1926.502 regulations.
2. APPLICATION
2.1 Purpose: The lag anchor is designed to be installed on a wood structure roof and used as single person PFAS anchor point to protect the user in a fall event.
The unit may be installed on roof trusses, on top of sheathing, with the base plate centered on a truss or rafter with a minimum nominal size of 2" by 4".
Installation fasteners, either Grade 5 SPAX® PowerLags™ 1/4" x 3" lag screws, or Simpson Strong-Tie® Strong Drive® 1/4" x 3" lag screws, are
provided. Use only the fasteners specified.
The anchor may also be used as an anchor for restraint applications.
The anchor is reusable provided there has been no fall arrest load and the unit passes the inspection procedures in Section 7 of this manual.
DO NOT use the anchor to lift tools or materials.
2.2 Personal Fall Arrest System Application: PFAS typically include an anchorage, a Full Body Harness (FBH), and a deceleration device such as a
SAL, an SRD, or a Fall Arrestor Connecting Subsystem (FACSS) when used with a rope grab/SAL. For PFAS applications, the anchor is installed on
the roof field. See Figure 2A. Maximum permissible free fall in PFAS applications is six feet.
2.2.1 Restraint Application: Restraint systems are designed to prevent the user from reaching a fall hazard area, as shown in Figure 2B. The anchor
may be used as part of a restraint system. See the restraint system manufacturers user instruction manual for connecting and use details.
2.3 Application Limits: The anchor is subject to load direction restrictions and placement restrictions. Use only the fasteners specified. See
Section 4 for complete installation details.
2.4 Rescue: Rescue operations require specialized equipment that is beyond the scope of this manual. An employer is required to have a written rescue
plan, the means to implement it, and the ability to communicate that plan to users, authorized persons, and to rescuers. See ANSI Z359.4-2007.
3. SYSTEM REQUIREMENTS
3.1 Capacity: Limit user weight to 130 - 310 lbs., (59 - 140.6 kg), including clothing, tools, etc. No more than one PFAS may be attached to one
anchor at any time.
3.2 Compatibility Of Connectors: Connectors are considered compatible with connecting elements when they have been designed to work
together in such a way that their sizes and shapes do not cause their gate mechanisms to open inadvertently, regardless of how they become
oriented. Contact FallTech if you have any questions about compatibility. Connectors must be compatible with the anchorage or other system
components. Do not use equipment that is not compatible. Non-compatible connectors may unintentionally disengage. Connectors must be
compatible in size, shape, and strength. ANSI and OSHA require self-closing, self-locking snap hooks and carabiners. See Figure 13 in Appendix B
for common incorrect connections to avoid.
DO NOT attach rebar hooks to this anchor. A side load on the gate may cause an unintentional disengagement. Use only self-closing, self-locking
snap hooks and carabiners.
3.3 Compatibility Of Components: Equipment is designed for use with approved components and subsystems only. Substitutions or
replacements made with non-approved components or subsystems may jeopardize compatibility of equipment and may affect the safety and
reliability of the complete system.
