Fischer FAZ II Throughbolts

The Fischer bolt anchor FAZ II is a steel anchor for the highest requirements. Heavy loads can be secured in cracked concrete using the steel anchor.

The FAZ II is easy to install and can be used extremely flexibly. The tried-and-tested expansion clip safely introduces the loads into the concrete and enables top load-bearing capacity.

The steel anchor is ideal for the anchoring of railings, cable trays, and cantilevers, for example.
