Prior to installation, plan your system:
1. Ensure selected installation location(s) for Metal Energy Absorber HLL system(s) will withstand minimum
loads as specified by this instruction manual.
2. ALWAYS make considerations to eliminate or reduce swing fall hazards.
3. Fall clearance for each installation location MUST be calculated by a Qualified Person, and MUST be
considered in the selection of PFAS equipment.
4. Ensure all components of PFAS are selected and deemed compatible with Metal Energy Absorber HLL
system by a Competent Person.
5. Ensure entire HLL system design and installation is done under supervision of Qualified Person. NEVER judge
HLL tension by eye; ALWAYS measure line sag and keep in concordance with sag requirements specified by
this instruction manual. NEVER over-tighten cable. Proper sag in cable reduces forces of Fall Arrest.
6. If performing installation at heights over 6’, ALWAYS use a complete and independent PFAS until
Metal Energy Absorber HLL System is fully installed and able to withstand forces of Fall Arrest as specified by this
instruction manual. Always maintain 100% tie-off.
Guardian recommends using 3/8” diameter cable. DO NOT use vinyl/plastic coated cable.
MINIMUM 1 Metal Energy Absorber required for systems up to 60’. MINIMUM 2 Metal Energy Absorbers
required for systems longer than 60’. Entire HLL system MUST NOT span more than 100’.
Installation and Use
Installation:
Tools needed for installation:
• 5/16” (8mm) wrench, 3/4” (19mm) wrench, 19/32” (15mm) wrench, Adjustable wrench, Torque wrench
(capable of measuring foot-pounds).
1. Select locations for all anchor points in HLL system. Ensure anchor points meet stated strength
requirements. Ensure proper fall clearance exists for entire system.
2. Lay out as much of HLL system as possible prior to attaching it to anchorage connectors.
