The disc lock is a special form of the padlock with some distinct advantages. The disc shape effectively combats the most common ways of forcing it open. The design means that there is only a small opening in the shackle, which makes it very difficult to tamper with. As the ABUS disc lock is made mainly of stainless steel, it is used especially where security and protection against corrosion are required.
The Diskus® family is available in models with diameters between 50 and 80 mm. The original disc lock is only available from ABUS. As a special model, the locks can be fitted with a disc cylinder (ABUS-Plus locking system) and cylinder pulling protection.
