These locks offer Ideal protection against bolt cutter attacks. The extra heavy duty 2-7/8" wide padlocks are ideal for all outdoor applications when needing multiple locks that utilize ONLY one key. The same key opens all locks. Each lock comes with two keys, therefore you will receive a total of four keys with the purchase of this 2 pack. ProSeries Reinforced Zinc Die-CastWhy Zinc Castings? For countless decorative and functional applications no other material and process can match the properties and economics of zinc die casting.Toughness: Few materials provide the strength and toughness of zinc alloys. Impact resistance is significantly higher than cast aluminum alloys, plastics, and grey cast iron.Strength & Ductility: Zinc alloys offer high strengths (to 60,000 psi) and superior elongation for strong designs and formability for bending, crimping and riveting operations.Anti-Sparking: Zinc alloys are non-sparking and suitable for hazardous location applications such as coal mines, tankers and refineries

- ATTENTION: If you order two 2-packs they will NOT necessarily be keyed the same. To ensure you get two 2-packs keyed alike, you must order the 4-pack.
