Lock technology: ASSA ABLOY door locks for every requirement

Professional lock technology needs solutions for various purposes – from office doors to high-security areas. Modern door locks must adapt flexibly to different installation situations and meet high quality standards.

ASSA ABLOY (Schweiz AG) develops and produces high-quality door locks under the MSL brand. FlipLock locks are suitable for demanding security systems with tubular frame doors, while CASA mortise locks and Tribloc multi-point locking systems are suitable for solid leaf doors. DELTA locks are specially designed for tubular frame doors in industrial and metal construction. 

All products comply with the current security and safety standards for escape routes, burglary and fire protection as well as for use in public buildings.
