GERW-S

Gerber clutch GERW stainless steel

Connectors Gerwe are suitable for common gripping girders.

Moreover, transverse forces in the vertical direction can absorb forces in the direction of the beam, and are therefore suitable for redirecting force. Depending on the load can be used both partial and full nailing.
