Description

Specification
Highest load capacities and efficient mounting. Ideal for fastening metal structures in concrete, A4 stainless steel | Extremely flexible to use due to three anchorage depths

Fastening can be adjusted up to twice after installation, for example in order to align railings or anchor plates (please refer to the assembly guide)

Very high loads

Smallest spacing and edge distance thanks to very low expansion effect
