2.8 MAKING CONNECTIONS: All connections must be compatible in size, shape, and strength. See Figure 4 for examples of
inappropriate connections. Do not attach snap hooks and carabiners:
A. To a D-Ring to which another connector is attached.
B. In a manner that would result in a load on the gate. Large-throat snap hooks should not be connected to standard-
size D-Rings or other connecting elements, unless the snap hook has a gate strength of 16 kN (3,600 lbf) or greater.
C. In a false engagement, where size or shape of the connector or connecting element is not compatible and, without
visual confirmation, would seem to be fully engaged.
D. To each other.
E. Directly to webbing or rope lanyard or tie-back material, unless the instruction manuals for both the lanyard and
connector specifically allow such a connection.
F. To any object whose size or shape does not allow the connector to fully close and lock, or that could cause connector
roll-out.
G. In a manner that does not allow the connector to align properly while under load.
