Anti-drop device AS-D

The catch device for 100% protection against falling door panels or machine guards

The question of safety is a criterion that cannot be ignored whatever the type of door or guard. According to the European Standards for doors (Directive for building products), all manually and power-operated doors that have a vertical movement must be fitted with an approved anti-falling device. The Butzbach Protection System provides an ideal safety system for many applications.
Simple installation allows trouble-free fitting to stacking doors, hinged doors, counter-balanced doors, sectional doors, roller doors, roller shutter doors, noise protection doors, powered windows and machinery guards. They can be fitted to new or retro-fitted to existing installations.
