A connector is considered compatible with the portable truss anchor when they have been designed to work
together in a manner that the gate mechanism cannot accidentally be opened no matter how they become
oriented.
•
Connectors must be compatible with the attachment point and must be capable of supporting a minimum of
5000 pounds. Do not use a non-compatible connector as it may unintentionally disengage. Connectors must
be compatible in strength, size, and shape. Self-locking snap hooks and carabiners are required by ANSI and
OSHA.
B.
Connections:
•
Only use of snaphooks and carabiners meeting ANSI Z359.1-2007 3.2.1.4 are permitted for use with this
equipment. This requires that "snaphooks and carabiners shall be self-closing and self-locking and shall be
capable of being opened only by at least two consecutive deliberate actions". Furthermore, "the gate of a
snaphook or carabiner shall be capable of withstanding a minimum load of 3,600 pounds without the gate
separating from the nose of the snaphook or carabiner body by more than .125 inches". All connectors must
be compatible in size, strength, and shape. Ensure all connectors are fully closed and locked.
•
Snap hooks and carabiners shall never be connected:

Personal Fall Arrest System:
•
A full body harness must be worn when this equipment is used as a component of the fall arrest system.
•
OSHA requires that a fall arrest system must be capable of arresting the user's fall with a max arresting force
(MAF) of 1800 pounds. DFP designed this system with a max limit of 900 pounds.
•
OSHA requires that the free fall limit is 6 feet or less.
•
This system has been designed for use with a web or cable style self-retracting lifeline. Lanyards are not
permitted to be used with this system.
D.
Anchorage Strength:
•
The required strength is dependent on the type of application that is being used. ANSI Z359.1 requires
systems to have a strength capable of sustaining static loads as follows:
o
o
•
If multiple systems are being attached to the same anchorage point in any of the prior applications, the
strengths defined shall be multiplied by the number of systems attached to the anchorage.
•
WARNING: The anchorage connector shall be marked or labeled with its intended application. Use of
equipment for an application that does not meet the strength requirements can result in serious injury
or death.

In a way that would result in a load on a gate.
In false engagement where features that protrude from the connector catch on the anchor and seems
to be fully engaged without visual confirmation.
To each other.
Directly to webbing, rope lanyard, or tie-back.
To any object which will not allow the connector to close and lock or which a roll-out could occur.
Fall Arrest:
(a) 5000 pounds for non-certified anchorages
