Anchor Clamps must only be used on structures capable
of supporting at least at least 5,000 pounds (22.2 kN)
per employee attached, or shall be designed, installed,
and used as part of a complete personal fall arrest system
which maintains a safety factor of at least two, under the
supervision of a qualifi ed person.

or harsh solutions which may have a harmful effect.
Contact 3M Technical Service with any questions.

Compatibility Limitations
All 3M Manuclave Anchor Clamps must only be coupled to
compatible connectors. OSHA's 29 CFR 1926.502 prohibits
snaphooks from being engaged to certain objects unless two
requirements are met: it must be a locking type snaphook,
and it must be "designed for" making such a connection.
"Designed for" means that the manufacturer of the snaphook
specifi cally designed the snaphook to be used to connect to
the equipment listed. The following connections must be
avoided, as they are conditions that can result in rollout when
a nonlocking snaphook is used:
• Direct connection of a snaphook to horizontal lifeline.
• Two (or more) snaphooks connected to one D-ring.
• Two snaphooks connected to each other.
• A snaphook connected back on its integral lanyard.
• A snaphook connected to a webbing loop or webbing
lanyard.
• Improper dimensions of the D-ring, rebar, or other
connection point in relation to the snaphook dimensions
that would allow the snaphook keeper to be depressed by
a turning motion of the snaphook.
Performance
All Manuclave Anchor Clamps meet a 5,000 lb. tensile load.
