To determine the clearance required:
Measure the distance from the user’s harness dorsal connection to the
anchorage for the Rebel SRL. Both horizontal and vertical distances are required. Use Figure 3A above to determine the
required clearance between the working level and the nearest obstruction. The dotted lines in the figure represent 1 foot (0.3
m) increments from the user’s harness dorsal connection to the anchorage. For example, 7 ft (2.1 m) of clearance is required
when the Rebel unit is anchored 3 1/2 ft (1 m) above and 3 1/2 ft (1 m) to the side of the user’s harness dorsal connection.
NOTE:
The clearances provided above assume the fall occurs from the standing position. If the worker is kneeling or
crouching an additional 3 ft (0.9 m) of clearance is needed.
2.15 COMPATIBILITY OF CONNECTORS:
Connectors are considered to be 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 inadvertently open regardless of how they become oriented. Contact 3M Fall
Protection if you have any questions about compatibility.
Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lbs. (22.2 kN).
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 (see Figure 4). Connectors
must be compatible in size, shape, and strength. Self-locking snap hooks and carabiners are required by
ANSI Z359 and OSHA.
