2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS: Capital Safety equipment is designed for use with Capital Safety
approved components and subsystems only. Substitutions or replacements made with non-approved
components or subsystems may jeopardize compatibility of equipment and may effect the safety and
reliability of the complete system.
2.2 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 Capital
Safety 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 8. Connectors
must be compatible in size, shape, and strength. Self- locking snap hooks and carabiners are required by
ANSI Z359.1 and OSHA.
2.3 MAKING CONNECTIONS: Use only self-locking snap hooks and carabiners with this equipment. Use only
connectors that are suitable to each application. Ensure all connections are compatible in size, shape and
strength. Do not use equipment that is not compatible. Ensure all connectors are fully closed and locked.
Capital Safety connectors (snap hooks and carabiners) are designed to be used only as specied in each
product’s user’s instructions. See Figure 9 for inappropriate connections. Capital Safety snap hooks and
carabiners should not be connected:
To a D-ring to which another connector is attached.
A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate.
NOTE: Large throat snap hooks should not be connected to standard size D-rings or similar objects which will
result in a load on the gate if the hook or D-ring twists or rotates, unless the snap hook complies with ANSI Z359.1
or ANSI Z359.12 and is equipped with a 3,600 lb (16 kN) gate. Check the marking on your snap hook to verify that
it is appropriate for your application.
C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the
anchor, and without visual conrmation seems to be fully engaged to the anchor point.
D. To each other.
E. Directly to webbing or rope lanyard or tie-back (unless the manufacturer’s instructions for both the
lanyard and connector specically allows such a connection).
F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and
lock, or that roll-out could occur.
G. In a manner that does not allow the connector to align properly while under load.
2.4 CONNECTING SUBSYSTEMS: Connecting subsystems (self- retracting lifeline, lanyard, rope grab and
lifeline, cable sleeve) must be suitable for your application. See Section 1.1. See subsystem manufacturer’s
instructions for more information. Some harness models have web loop connection points. Do not use
snap hooks to connect to web loops. Use a self-locking carabiner to connect to a web loop. Ensure the
carabiner cannot cross-gate load (load against the gate rather than along the backbone of the carabiner).
Some lanyards are designed to choke onto a web loop to provide a compatible connection (see Figure 10).
Lanyards may be sewn directly to the web loop forming a permanent connection. Do not make multiple
connections onto one web loop, unless choking two lanyards onto a properly sized web loop.
Figure 8 - Unintentional Disengagement Figure 9 - Inappropriate Connections
If the connecting element to which a snap hook (shown) or carabiner attaches
is undersized or irregular in shape, a situation could occur where the connecting
element applies a force to the gate of the snap hook or carabiner. This force may
cause the gate (of either a self-locking or a non-locking snap hook) to open,
allowing the snap hook or carabiner to disengage from the connecting point.
Small ring or other
non-compatibly
shaped element
Force is applied to the
Snap Hook.
The Gate presses against
the Connecting Ring.
The Gate opens allowing
the Snap Hook to slip off.
