1. DESCRIPTION
The FallTech® 6' DuraTech™ Web SRD is a self‐retracting lifeline for those working at height. At the top of the unit, a swiveling aluminum eye provides an
attachment point for a self‐closing and self‐locking connector. The SRD body consists of a glass‐filled nylon housing that contains a 6' length of high
performance polyethylene and polyester fiber webbing wound onto a spring‐tensioned drum. The attachment end of the webbing may be configured with
a variety of sewn‐on connectors. A stitched fold in the lifeline between the housing and the leg end connector functions as a retraction stop and a fall
arrest impact indicator. If the stitching is torn loose, remove the unit from service.
When attached and the worker moves about, the lifeline pays out and retracts, automatically maintaining a taut line. If a fall occurs, a centrifugal system
engages a lock mechanism that applies a disc brake, slowing and arresting the fall.
For purposes of this manual, the 6' DuraTech Web SRD may be referred to as the equipment, the device, the product, or the unit. See Tables 1‐A, 1‐B and
1‐C, and Figure 1 in Appendix A. It is recommended that the user of the equipment discussed in this manual read and understand the entire manual before
beginning work.
1.2 Appendices A and B: This manual contains two Appendices, Appendix A and Appendix B. Appendix A contains figures and tables specific to the 6'
DuraTech Web SRD discussed in this manual. Appendix B contains figures and tables applicable to fall protection equipment in general.
1.3 ANSI Standards and OSHA Regulations: ANSI standard Z359.14 sets performance requirements for SRDs, based on dynamic testing, and is comprised of
two classifications; Class A, and Class B. The SRD discussed in this manual has been tested to and conforms to ANSI Z359.14 standards for a Class B device.
These tests include Dynamic Performance Testing, Dynamic Strength Testing, Static Strength Testing, and Retraction Tension Testing. The SRD was also
tested for Static Strength per OSHA regulations. See paragraph 3.5.1.
2. APPLICATION
2.1 Purpose: An SRD is designed for use as a component in a 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 or any application where fall protection and worker mobility is required.
The DuraTech SRD is intended for Personal Fall Arrest applications only. The SRD is not designed nor suited for use in restraint, personnel riding,
suspension, work positioning, or rescue applications. Do NOT use the SRD for these applications except as a back‐up PFAS.
2.2 Personal Fall Arrest System: A PFAS is typically composed of an anchorage and a FBH, with an energy absorbing connecting device, i.e., a SAL, an SRD,
or a Fall Arrester Connecting Subsystem (FACSS), attached to the dorsal D‐ring of properly fitted and adjusted FBH. All uses and applications of a FBH with this
equipment requires the FBH to be properly fitted and adjusted to the user. Failure to properly fit the FBH to the user could result in serious injury or death.
The SRD may be installed on a FBH, or attached to a suitable anchorage. See Section 4 for additional details.
2.3 SRD Orientation in Fall Arrest: The 6' SRD is a versatile design, capable of multiple attachment orientation options, either as a single‐leg unit, or as a
twin‐leg unit, as shown in Figures 2A, 2B, and 2C of Appendix A.
2.3.1 Single SRD: One SRD with two orientation options;
 As a single‐leg SRD with the housing end attached to the dorsal D‐ring of a FBH and the leg end connected to an anchorage. The anchorage may be
anywhere in the allowable anchorage range, from overhead (directly overhead to the level of the D‐ring) to non‐overhead (from the level of the D‐ring
to a maximum of 2' below the D‐ring). See Figure 2A in Appendix A.
 As a single‐leg SRD with the housing end attached to an anchorage and the leg end connected to the FBH dorsal D‐ring. The anchorage may be
anywhere in the allowable anchorage range, from overhead (directly overhead to the level of the D‐ring) to non‐overhead (from the level of the D‐ring
to a maximum of 2' below the D‐ring). See Figure 2B in Appendix A.
2.3.2 Twin‐leg SRD: A twin‐leg SRD is utilized with the housing ends worn on the FBH as shown in Figure 2C in Appendix A. The leg ends are connected, one
at a time for 100% tie‐off, to an anchorage within the correct orientation range.
