Additionally, the Mul-T-Lock Hasp Lock, although more accurately belonging to the C-series family, due to its dimensions, offers the highest grade protection.  In fact our Hasp Lock is so dynamic that it earned a security grade 6 certification, the highest possible ranking within the EN 12320 standard, a prestigious European Standard Institution.
