The Master Lock Excell discus padlocks feature a 70 mm wide stainless steel body for maximum strength, reliability and corrosion resistance. The fully shrouded design minimises shackle exposure and protects against bolt cutter attacks. The 10 mm in diameter octagonal shackle is 16 mm long and made of Tough-Cut boron-carbide, which is 50% harder than hardened steel for maximum resistance to cutting and sawing. The 4-pin cylinder prevents picking and the dual ball bearing locking bar ensures maximum resistance to prying and hammering. The covered keyway provides maximum weather protection, and the reinforced body bumper protects against scratches. Delivery includes 2 padlocks and 4 keys.
