Fall Protection Anchor Systems

Eyebolts are a widely used and effective solution for fall protection when working at height. Suitable for installation into brick, masonry, concrete, steel, timber, or cavity walls, they can serve as restraint, work positioning, or fall arrest anchors — but must only be used for the purpose they were originally installed for. Each eyebolt is fitted with a clearly marked warning disc to identify its intended use.

All TETRO-installed eyebolts are fitted by independently trained and certified professionals in line with AS/NZS 1891.4:2009, the New Zealand Code of Practice, and relevant manufacturer specifications.

Installation & Testing

Each eyebolt is installed using a knurled threaded sleeve secured with a two-part resin system. Once cured, the eyebolt is torqued to specification and pull-tested in the direction of load to verify secure anchorage. Eyebolts used for work positioning may also be installed into structural steel.

Anchors must withstand a combined minimum load of 15kN (1500kg) and are tested using calibrated test equipment on-site.

Positioning for Safety

Correct placement of eyebolts is critical. As specialist rope access contractors, TETRO has extensive experience in determining the safest and most practical positioning — whether for single-point work or larger areas requiring multiple anchor points. Twin lanyards may be needed to maintain 100% tie-off during movement.

When used for work positioning or rope access, eyebolts must always be used in pairs to allow for continuous backup. Under no circumstances should a person be suspended from a single eyebolt. In rescue scenarios, two users may be temporarily suspended from a pair of eyebolts.

Recertification & Inspection

  • Annual inspection is required by a competent person authorised by the manufacturer.

  • Six-monthly inspection is required when used for rope access or work positioning tasks.
