Step 1:
Determine the location of the end anchorages and, in accordance with Section 3.2, evaluate their strength. Determine the span
length of the system and determine the minimum required clearance for safe use in accordance with Section 2.7.
Step 2:
Install the end anchorage connectors. The FallTech 4-Person Temporary HLL system comes with 2 pass-through anchor straps for
wrapping around columns. If using pass through anchor straps, ensure strap is wrapped at least twice around the end anchorage, see
Figure 9. This will help prevent sliding of the anchor straps during use. If using alternative anchorage connectors, please ensure the
connectors are compliant and conform to the requirements of Section 3.2. Not all anchorage connectors are designed for use with
horizontal lifeline systems. In all cases, refer to the user’s instruction manual for the end anchorage connectors to be used.
Step 3:
Secure the HLL system to the anchorage connectors with the provided end attachment carabiners.

Product Assembly and Installation:
System installation requires end anchor points that are a minimum of 6,000 lbs. (26.7 kN) in both
vertical and horizontal directions for three and four workers and 5,000 lbs. (22.2 kN) for one and two workers, see Figure 8. The
lifeline shall be installed to limit free fall to 6’ or less*. When using SRDs the lifeline must be positioned overhead. The horizontal lifeline
should be positioned in a manner to minimize free fall while allowing ease of use. Movement away from the lifeline should be limited
to reduce the potential for swing fall. Lifeline end anchors should be installed at approximately the same elevation so that the lifeline
itself is not sloped more than 5 degrees.
