Roto Safe H is our mechanical multi point locking system for main entrance doors, on which the main lock and the additional locking points in the first step are locked with a door lever handle. In the second step, the system is blocked with a key. With a unique combination locking system consisting of the power wedge and bolt on what is currently the most efficient Roto Safe lock generation 600, it locks all main doors from backset size 25 mm both reliably and permanently tight: against heat, wind and cold, as well as against unauthorised access. In this way, all what you do not want to take inside, must stay outside!
