Locks HS - "High security" - in this section we offer locks, elements, accessories, which create the locking systems with the highest security and we will do our best to explain why this is so - because not every expensive lock is HS, but HS locks in any case are expensive.This section requires basic technical knowledge in order to complete one HSL system. The elements of one HSL system have the relevant certificates against unautorised entry. For the mechanical locks the highest gade is 7 or "C" according to EN 1300/EN 12209:2004.
