Devices intended to form the interface between the fall arrest system (harnesses, lanyards, retractable lanyards etc.) and the structure. These can be in the form of single bolts, slings, deadweight devices or anchor systems (rails or cables). EN 795: 2012 (1 user) & CEN/TS 16415: 2013 (2+ users) classifies anchor devices in the following manner:
- Type A – anchor device with one or more stationary anchor points, while in use, and with the need for a structural anchor(s) or fixing element(s) to fix to the structure
- Type B – anchor device with one or more stationary anchor points without the need for a structural anchor(s) or fixing element(s) to fix it to the structure
- Type C – anchor device employing a flexible anchor line which deviates from the horizontal by not more than 15° (when measured between the extremity and intermediate anchors at any point along its length)
- Type D – anchor device employing a rigid anchor line which deviates from the horizontal by not more than 15° (when measured between the extremity and intermediate anchors at any point along its length)
- Type E – anchor device for use on surfaces up to 5° from the horizontal where the performance relies solely on mass and friction between itself and the surface.
