The BRÜHL-GRK® mounting system is the standard mounting system for the precise fitting of safety switches on BRÜHL swing doors. The safety switch is mounted from the outside of the machine at the height of the sturdy plastic handle. The system is characterized by an optional ball catch, which is used according to the Brühl product recommendation for safety switches whose latching force is less than 30 N. The add-on system can be used for both right-hinged and left-hinged doors. The BRÜHL handle system can be combined with various manufacturer-independent safety switches. We trust in products of the companies Bernstein, Honeywell, ABB, Pilz, Schmersal, Siemens, Rockwell Automation.
