All our products are tested not only in accredited testing laboratories for their resistance to various methods of breaking and their lifespan, but they are all also trialled directly in our company. The products are tested in a dusty environment, in water, grease and even in a salt-spray cabinet where they outperform the applicable standards severalfold. Our tests show that our products are particularly suitable for external use where they withstand extreme climatic conditions over a long period of time. The official as well as our own tests also prove a long lifespan, which is the time during which the product must provide quality and reliable service even under a lot of strain. This fact can be appreciated especially with regards to front doors of flats and houses or various company premises that are locked and unlocked a number of times a day.
Our claim is supported by a 5-year guarantee that we provide with all TOKOZ PRO products.
