Highest load values at low spacing and edge clearances
Extra-large effective anchorage depths maximise the already high load values per anchor
Quick installation with fewer reinforcement hits
Extra-small effective anchorage depths minimise the drilling and setting time
Economical and flexible application
Freely selectable embedment depth allows optimum utilisation of the anchors depending on the embedment depth and application
Minimum edge distance and spacing
Allows for near-edge fixings, small anchor plates and installation in thin concrete parts
For earthquake-proof construction

| 1) The partial safety factors of the resistances regulated in the ETA and a partial safety factor of the effect of γF = 1.4 have been taken into account. Please refer to the European Technical Assessment ETA-20/0229 2) for information on combining tensile and transverse loads, edge influence and groups of anchors 2) Use with anchoring depths hef < 40 mm is limited to the anchoring of statically indeterminate systems under the condition of dry interiors 3) The concrete has normal reinforcement. Higher values are possible for higher concrete compression strengths | ||||||||||||||
