1. DESCRIPTION
The FallTech® WrapTech® 7'/9' Mini Single/Twin SRD is a self-retracting lifeline for those working at height and subject to fall hazards. The
WrapTech Single/Twin is specifically designed for instances where traditional anchoring options are limited, for users with a combined (clothing,
tools, etc.) total weight of between 130 lbs and 310 lbs only.
This manual contains two Appendices, Appendix A and Appendix B. Appendix A contains figures and tables specific to the SRD discussed in this
manual. Appendix B contains figures and tables applicable to fall protection equipment in general. All figure, table, and chart references in this
manual are to Appendix A unless otherwise noted. All section and paragraph references are to this manual unless otherwise noted. The user of the
equipment discussed in this manual must read and understand the entire manual before beginning work.
For purposes of this manual, the SRD may be referred to as the SRD, the equipment, the device, the product, or the unit. The terms wrap-back,
wrapped, tied back, and tie-back are used interchangeably.
At the top of the unit, a swiveling steel eye provides an attachment point for a self-closing and self-locking connector. The SRD body consists of a
nylon housing containing Dyneema webbing wound onto a spring-tensioned drum. The drum is equipped with a pawl system that locks the drum
shaft and halts lifeline payout in a fall event.
Below the housing is an Energy Absorber (EA) to absorb the energy of a fall event, slowing and arresting the fall. The EA also functions as a fall
event indicator. Below the EA is an additional 3' of jacketed webbing, which is equipped with a specially designed connector. The jacket on the
lifeline supplies abrasion protection for the lifeline when it's wrapped around an anchorage structure, and provides a 7'/9' operational lifeline. The
special carabiner is designed to attach back onto the jacketed portion of the lifeline. The jacketed length of lifeline is not held inside the housing.
The jacket on the lifeline is designed to provide abrasion protection on an anchorage structure. Do not use the jacketed portion of the lifeline on
See Tables 1-A and Figure 1.
1.1 OSHA Regulations: The device discussed in this manual complies with OSHA 1926.502 Safety and Health Regulations for Construction Fall
Protection. The SRD was also tested for Static Strength per ANSI standards and 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 work, or any application where fall protection and worker mobility is
required. 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 part of 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 must be installed on an approved FBH. See Section 4 for additional details.
2.3 SRD Orientation In Fall Arrest: The WrapTech SRD is a versatile design, with multiple attachment options with approved connectors, as shown
in Figure 2A, Panels A, B, C, and D.
