Description
The MSA PointGuard Concrete Anchorage Connector is a component designed specifically for
coupling a single personal fall arrest system to an anchorage.

System Requirements
2.2.1
Compatibility of Components and Subsystems
PointGuard Concrete Anchorage Connector Straps are designed to be used with MSA approved
components and connecting subsystems. Use of the PointGuard Concrete Anchorage Connector
Straps with products made by others that are not approved in writing by MSA may adversely affect the
functional compatibility between system parts and the safety and reliability of the complete system.
Connecting subsystems must be suitable for use in the application (e.g. fall arrest or restraint). MSA
produces a complete line of connecting subsystems for each application. Contact MSA for further infor-
mation. Refer to the manufacturer's instructions supplied with the component or connecting subsystem
to determine suitability. For fall arrest applications using the PointGuard Concrete Anchorage
Connector Strap, the maximum fall arrest force must not exceed 1,800 lbf (8 kN). This will maintain a
2:1 safety factor for the system. Contact MSA with any questions regarding compatibility of equipment
used with the PointGuard Concrete Anchorage Connector Strap.
2.2.2
Compatibility of Connectors
Connectors, such as D-rings, snap hooks, and carabiners, must be rated at 5,000 lbf (22 kN) minimum
breaking strength. MSA connectors meet this requirement. Connecting hardware must be compatible
in size, shape, and strength. Non-compatible connectors may accidentally disengage ("rollout").
Always verify that the connecting snap hook or carabiner and the D-ring on the harness or anchorage
connector are compatible. Use only self-closing, self-locking snap hooks and carabiners with the
PointGuard Concrete Anchorage Connector Strap.
2.2.3
Anchorages and Anchorage Connectors
Anchorages for personal fall arrest systems must either: (a) have a strength capable of supporting and
withstanding at least 5,000 pounds (22.2 kN) in the directions permitted by the system without failure,
or (b), must be certified by a professional engineer as having the required strength for fall arrest or
travel restraint, as applicable. See ANSI Z359.18 for definition of certification. When more than one
personal fall arrest system is attached to an anchorage, the anchorage strengths set forth in (a) and
(b) must be multiplied by the number of systems attached to the anchorage. This requirement is consis-
tent with OSHA requirements under 20 CFR 1910, Subpart F, Section 1910.66, Appendix C. Do not
proceed with installation and use of the anchorage connector if an assessment of strength cannot be
made.
