1. DESCRIPTION
The FallTech® Chain Roof 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 Chain Roof Anchor is used by construction and maintenance personnel on residential and commercial roofs, and other locations where fall hazards exist.
The Chain Roof Anchor provides multiple options, with a wide variety of load applications for roofing and building maintenance. The Chain Roof 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 two steel anchoring plates riveted to a flexible rubber centerpiece. Each plate contains holes for nails and shaped holes for lag
screws or nails. A length of chain passes through a connection O‐ring, allowing the O‐ring to slide. Each end of the chain is fastened to an anchor plate with
a welded chain‐securing stud.
The anchor discussed in this manual meets all applicable OSHA 1926.502 regulations.
See Figure 1 and Table 1 in Appendix A.
This manual contains two appendices, Appendix A and Appendix B. Appendix A contains tables and figures specific to the Chain Roof Anchor.
Appendix B contains tables and figures for fall protection in general.
All figure and table references in this manual are to Appendix A unless stated otherwise.
For purposes of this manual the anchor and associated fasteners may be referred to as the chain roof anchor, the anchor, the product, the equipment, or the unit.
2. APPLICATION
2.1 Purpose: The chain roof anchor is designed to be installed on a wood structure roof and used as single person anchor point for a PFAS to protect the
user in a fall event. The anchor may also be used in pairs as the end anchors for a Horizontal Lifeline (HLL).
The anchor may also be used as an anchor for restraint applications.
Installation fasteners, twelve 16d nails, and six 1/4" x 2‐1/2" lag bolts, are provided. Installation fastener selection depends on ultimate application. See
Figure 2. Fasteners, nails or lag screws, must engage a truss or rafter.
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.
2.1.1 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. Maximum permissible free fall is six feet. See Figure 2.
The unit may be installed on the roof ridge to allow access to both sides of a peaked roof, or on the roof field for use on one side of the roof.
Two anchors may be installed on the field or ridge as an opposed pair and used as end anchors for an approved HLL system for multiple users. See Figure 3A.
2.1.2 Horizontal Lifeline Applications: An HLL fall arrest system typically includes two anchorage connectors, a lifeline tensioner, and the horizontal lifeline.
The HLL must be an approved unit such as FallTech HLL model numbers 777030, 777050, 777075, 777100, 770001, 770003, and 770006. HLL units must be used as
instructed according to the procedures detailed in the current edition of the FallTech User Instruction Manual for each model number. See Figure 3A and 3B.
2.1.3 Restraint Application: Restraint systems are designed to prevent the user from reaching a fall hazard area. These systems are of two types; a
restraint lanyard in conjunction with a manual rope adjuster or one equipped with a parking feature connected to a VLL, or a short tether attached to the
anchorage to prevent the user from reaching a fall hazard. No vertical free fall is permitted. See Figure 4.
2.2 Application Limits: The anchor is subject to load direction restrictions, dependent on installation fastener. See Section 4 for complete installation details.
2.2.1 Installed with Nails: The anchor may be installed on the ridge or on the field with the twelve provided 16d nails driven through the holes in the
anchor plates, through the sheathing, and into a truss or rafter. Installed with nails, the anchor is an OSHA compliant 3,600lb single point anchor.
Application is as follows;
Use on the Ridge – As a PFAS attachment point for an SRD, or a FACSS. See paragraph 2.1.1. The anchor installed with nails on the ridge provides user
access to both slopes of the ridge. On a low‐slope roof, the user has considerable mobility, but must remain aware of edges and swing fall hazards. On a
roof of normal slope, user mobility is limited to 30° on each side of the anchor's longitudinal (in line with anchor plates) centerline. See Figure 5B. Ensure
the chain and connection eye is straight down after crossing the ridge.
Use on the Field – Installed on the field, the anchor may be used for a single user in a PFAS or restraint application. Do not cross the ridge to work on the
other side. On a low‐slope roof, the user has considerable mobility on the one side, but must remain aware of edges and swing fall hazards. On a roof of
normal slope, user mobility is limited to below the anchor, and up to 30° on each side of the anchor's longitudinal (in line with anchor plates) centerline.
2.2.2 Installed with Lag Bolts: The anchor may be installed on the ridge or on the field with the six 1/4" x 2‐1/2" lag bolts driven through the lag bolt holes in the
anchor plates, through the sheathing, and into a truss or rafter. Installed with lag bolts, the anchor is an OSHA compliant 5,000lb anchor. Application is as follows;
