Ideal for outdoor accessories which must be uninstalled again, stainless steel A4

Extremely flexible to use

Three anchoring depths (sizes 6 – 14) and a large variety of types

Fastening can be adjusted up to twice after installation

(Sizes 8 – 14), for example in order to align railings or anchor plates (please refer to the assembly guide in the approval or the enclosed leaflet)

  • High load-bearing capacities

  • Virtually no expansion effect, enabling minimal axis and edge distances to be maintained

  • Very quick and easy to install

  • No installation torque required

  • Immediate load-bearing capacity – no waiting

From size 8, we recommend the use of a suitable tangential impact screwdriver for installation.

If several anchors are arranged behind each other in the same load direction, only one anchor is positioned for transverse loads.
