User Instructions - English
1. Locate and identify an approved compatible anchorage.
The beam or structure to which this product is attached
must be capable of supporting the loads specified in Sec
-
tion 2.2 of this manual in the direction of pull. Be sure that
the mounting location is clean and free of debris.
2. Locate or drill a 21/32” (16.7mm) diameter hole. Consider-
ation should be given to allow sufficient clearance to place
the lockwasher and tighten the nut.
WARNING: When the D-bolts are being installed paral-
lel or alongside the horizontal lifeline (see Fig. 1a), the
D-bolts must be mounted horizontally. D-bolts being
installed perpendicular to the lifeline (see Fig. 1b) may be
mounted at any angle.
WARNING: On D-bolts installed to W-Shaped beams (see
Fig. 1c), the mounting hole must be drilled perpendicular
to the flange. D-bolts installed to S-Shaped beams (see Fig.
1d) must be drilled perpendicular to the flange and a ta
-
pered (aka bevel, side hill or wedge) washer must be used
to ensure the D-bolt and/or nut and washer seats squarely
against the beam surface.
3. Mount the D-Bolt Anchor by passing the approved 5/8”
(16mm) stainless steel bolt through the hole in the connector
and through the hole in the structure
(see Fig. 1)
. Attach the
lockwasher and nut. Completely tighten making sure the en-
tire nut is engaged on the threads and the device is securely
fastened to the structure. Torque to 125 ft. lbs. (169Nm).
WARNING: Do not overtighten. Excessive tension can
cause damage to the anchorage system. Use recom-
mended torque value above.
Repeat these procedures to install D-bolt anchor on opposite
end of lifeline system.

4.0 Installation of Xenon Horizontal Lifeline Kits
• Before installation, carefully inspect all components of the system according to the manufacturer’s instructions (see 8.0
Inspection and Maintenance).
• Ensure that there is sufficient fall clearance below the work surface to avoid hitting a lower level or obstruction (see 6.0 Fall
Clearance).
• If installing the system off-the-ground, a personal fall arrest system including an anchorage connector, such as a Miller beam
anchor, must be used. Once a D-bolt anchor has been completely installed and secured to the beam or structure given the
required specifications, a worker may tie-off onto the anchor.
• Some system components may come preassembled. Installation instructions still must be followed to ensure all components
are included and properly assembled. All fasteners and connectors must be checked for correct alignment and installation
and tightened to required specifications.
