• Keying: The "SR1" designation means it is for use with a restricted SR1 keyway, typically found in master key systems. This allows locks in a group to be individually keyed, but all can be opened with a single master key.
• Body: The padlock has a durable, solid brass body that is resistant to corrosion for use in all-weather conditions.
• Shackle: It features a 5/16-inch diameter, 1-1/2-inch tall shackle made of molybdenum-hardened steel, which offers increased resistance to cutting.
• Locking mechanism: A double deadbolt locking mechanism provides extra security and prying resistance.
• Cylinder: It uses a 6-pin solid brass cylinder that is re-keyable, meaning it can be serviced and keyed to a different key.
• Keying type (D2300): The "D2300" part of the model number indicates that the padlock is "keyed different," meaning each padlock has a unique key.
