PRODUCT DESCRIPTION:
Figure 1 illustrates the 3M™ DBI-SALA® EZ-Line™ Horizontal Lifeline (HLL) system. The HLL System is secured between two
anchorage points and provides connections for up to two users as part of a Personal Fall Arrest or Fall Restraint System.
Figure 2 illustrates components of the 3M™ DBI-SALA® EZ-Line Horizontal Lifeline. See Table 1 for Component Specifications.
The EZ-Line Horizontal Lifeline is a tensioned steel cable lifeline terminated between Anchorage Connectors. The cable housing
contains an internal energy absorber to limit forces on the system and absorb energy in a fall arrest. Attachment O-rings provide
moving anchorage connection points for the user’s Personal Fall Arrest or Personal Fall Restraint system.

Anchorage
Requirements:
Figure 11 Reference Description Anchorage Requirements
A
In line with axis of HLL 5000 lbf (22.2 kN)
B
Perpendicular to axis of HLL 3600 lbf (16 kN)
End Anchors: Structure supporting the horizontal lifeline system must be rigid and capable of
supporting at least 5000 lbf (22.2 kN) along the axis of the horizontal lifeline. Anchorages must also
support at least 3600 lbf (16 kN) applied in all potential directions of fall arrest that are perpendicular to
the axis of the horizontal lifeline.
Intermediate Anchors (if used): Intermediate anchorages and supporting structure must support at
least 3600 lbf (16 kN) applied in all potential directions of fall arrest.
Capacity: Single Span System: The maximum capacity of a single span EZ-Line HLL is two persons. The
maximum weight of each person including tools and clothing is 310 lb. (140 kg).
Multi-span System: The maximum capacity of a Multi-span EZ-Line HLL is two persons per span with
a maximum of 6 persons provided the requirements of ANSI Z359.6 or CSA Z259.16 are met. The
maximum weight of each person including tools and clothing is 310 lb. (140 kg).
Connecting
Subsystems and
Fall Arrest System
Limits:
Energy Absorbing Lanyards or Self Retracting Devices (SRDs) connected to the system must weigh
no more than 15 lb. (6.8 kg). Each person’s connecting subsystem must limit maximum fall arrest
forces (MAF) to 1,350 lbf (6.0 kN) or less. Connecting subsystems must be used at anchorage heights
consistent with their instruction manuals.
