Notes
1. The total weight combinations for the anchor devices are;
2. The anchor device is for use where it is impractical to install constant force posts or rigid anchor posts to the
roof or supporting structure below.
3. The anchor device is for use on nominally flat roofs up to a maximum pitch of 5.
4. For situations where the arrest of a fall causes the anchor to move up a slope the maximum pitch of the roof
is 15.
5. The anchor device is supplied with four rubber coated base weights. These must be in contact with the roof
surface when it is fully assembled.
6. When used as part of a Type C horizontal lifeline system the maximum number of users connected to the
system must not exceed two (2).
7. When used as part of a Type C horizontal lifeline system, the maximum intermediate spacing between the
anchor devices is 10 m.
8. When connecting to the cable system always use a full body harness and energy absorbing lanyard to
appropriate national standards.
9. The anchor device must never be used during period when frost, ice or snow are present on the roof surface.
10. The anchor device must never be used if the roof surface is contaminated by grease, oil or any other type of
lubricant.
11. Refer to installation and user instructions 65642_99 for further information for use as an end anchor.
When used as a Type A single point anchor and a karabiner type connector is to be attached to the D-ring,
use D-ring 85030-00 or 85032-00
When used as a Type A single point anchor and a snap hook type connector is to be attached to the D-ring,
use D-ring 85032-00 this will avoid the connector from becoming unintentionally detached which is referred
to as ‘roll-out’
