MINIMUM substrate requirements:
• Wood: 3/4” CDX plywood (for all fasteners)
and 3“ support beam (for minimum 4 fasteners).
• Metal: 20 gauge.
• Concrete: 6” (must be 2,000 psi or greater).
*Wood and metal installations compliant with
OSHA only. Concrete installation compliant with
both OSHA and ANSI.
Adjustable Skyhook Anchor MUST install flush against substrate.
1. Determine desired location for anchor; ensure location is free of debris, rot, decay, cracking, and hazardous
materials. NEVER install on gable ends, fascias, rake ends, overhangs, bottom cords, collar boards, spliced
sections, or substrate incapable of withstanding application minimum loads. If unable to determine suitable
installation location, consult jobsite Qualified Person.
2. Make considerations for eliminating or minimizing swing fall hazards.
3. Adjustable Skyhook Anchor is compatible with roof pitches from flat to 12/12. ALWAYS measure roof pitch
prior to installation. NEVER use Adjustable Skyhook Anchor incompatible with roof pitch.
4. Adjustable Skyhook Anchors MUST be placed a MINIMUM 10’ from all leading edges of fall hazards.
5. Ensure all fasteners are those supplied by Guardian Fall Protection, or are deemed compatible by a
Competent Person. All fastener installation holes MUST be filled. Installations must be done directly on
substrate, and never through any intermediary substrates.
- If installing onto wood, a minimum of 4 fasteners must fully embed into truss or underlying support beam.
- If installing onto concrete, use qty. 15 fasteners per side. Fill two full rows closest to center (on each side).
- If removing and reinstalling a Adjustable Skyhook Anchor, fully inspect the anchor according to instruction
inspection specifications. DO NOT reuse if any signs of damage or defects are found. ALWAYS use new
fasteners for each new installation application.
