Depending on the purpose of the installation, there are several possibilities for fixing our swivel bracket.

In tunnel construction, the swivel bracket can be fastened to either a convergence bolt with a WILD-plug-in adaptor (Order No. 5 KBW), or to a connection adaptor with a predetermined breaking point (Order No. 5 KB + 46-VA). The connection adaptor option is particularly safe because the convergence bolt, being set in concrete, is not damaged even when there is a heavy mechanical load. In the event that a construction vehicle should collide with a swivel bracket, usually only the adaptor will break and, in most cases, the bolt and swivel bracket will remain undamaged.
For other applications, our 11R-series wall bolts can be combined with the WILD-adapter, Order No. 11 R5-W. In some cases, where highly visible marking is not essential, a simple brass pin may be sufficient.
