declared a Class 1 and Class 2 device, ANSI requires an SRD to have an overhead Arrest Distance of less
than 42” (1.1 m), an Average Arrest Force of less than 1,350 lbs (6 kN) [1,575 lbs (7 kN) conditioned]
and a Maximum Arresting Force of 1,800 lbs (8 kN), for both ambient and conditioned testing. When
dynamically tested in accordance with requirements of ANSI Z359.14-2021, FallTech Class 1 and Class
2 Self-Retracting Devices have an AAF of 1,350 lbs (6 KN) or less and an AD of less than 42” (1.1 m).
Please see Section 5 of this user instruction manual for how to calculate your Minimum Required Fall
Clearance (MRFC).
3.0 Application
3.1 Purpose:
The FallTech DuraTech Cable SRL is designed to be used as a component in a Personal Fall Arrest
System (PFAS), to provide a combination of worker mobility and fall protection as required for
inspection work, general construction, maintenance work, oil production, confined space work, etc.
The SRD is intended for Personal Fall Arrest applications only.
3.2 Personal Fall Arrest System:
A PFAS is an assembly of components and subsystems used to arrest a person during a fall event.
A PFAS typically consists of an anchorage, a deceleration device such as a Shock Absorbing Lanyard
(SAL), a Self-Retracting Device (SRD), or a Fall Arrestor Connecting Subsystem (FACSS), and a properly
fitted Full Body Harness (FBH). Maximum permissible free fall in a typical PFAS is 6’. The Self-Retracting
Devices discussed in this manual are intended for overhead use. Other applications may be below the
D-ring, or horizontally in an approved FallTech SRD rotating anchor, designed for such use.
3.3 Horizontal Lifeline (HLL) and Rail Systems:
The SRD may be attached to rigid and flexible anchors provided that all HLL or rail system applications,
installation, and uses are under the supervision of a Qualified Person.
3.4 Rescue:
Ensure a written rescue plan, method and system is in place and readily available for rapid response.
Rescues may require specialized equipment or measures. Rescue operations are beyond the scope of
this manual. See ANSI Z359.4 and Z359.2.
3.5 Application Limits:
Take action to avoid moving machinery, sharp edges, abrasive surfaces, and thermal, electrical,
including the arc from welding applications, and chemical hazards as contact may cause serious
injury or death. The SRD is not designed for use in restraint, personnel riding, suspension, or work
positioning. Rescue applications are beyond the scope of this manual. Do not use the SRD for these
applications except as a back-up PFAS. The SRD discussed in this manual is not designed for Leading
Edge applications.
4.0 System Requirements
4.1 Capacity:
The SRD is designed for use by a single user with a combined weight of user, tools, clothing, etc., of 130
– 310 lbs. (59-141 kg).
4.2 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 FallTech if you have any
questions about compatibility. 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. Connectors must be compatible in size, shape, and strength. Self-closing,
self-locking connectors are required by ANSI and OSHA.
