The round design, narrow shackle opening, and welding seam ensure solid safety! This 60mm padlock protects your valuables stored in trucks, vans, basements, or behind factory gates. The lock is made of stainless steel inside and out, and the shackle is made of special hardened steel, which makes it particularly resistant to picking. The seam that holds the two stainless steel housing pieces together is hand-welded on every Diskus 24/60; this means that the two halves cant be easily broken apart, and the Diskus secures your valuables and items very well. Two keys are included in the scope of delivery.
