The MASTER LOCK 6830 is a Pro Series brass padlock designed for security applications requiring a keyed-different configuration. The body is constructed from solid brass, measuring 1-9/16 inches wide and 1-31/32 inches high. The boron alloy shackle provides enhanced cut resistance, with a diameter of 1/4 inch, a clearance height of 1-1/16 inches, and a width of 25/32 inches. A 5-pin tumbler cylinder delivers reliable pick resistance. This padlock is installed by maintenance technicians, facilities staff, and trade professionals securing equipment panels, gates, hasps, and lockout points.
The 6830 is suited for light industrial, commercial, and residential applications where brass corrosion resistance is a requirement. Common uses include securing electrical enclosures, HVAC service panels, storage units, and outdoor fixtures. The keyed-different configuration means each lock operates on its own unique key, making it appropriate for multi-point access control scenarios where individual keying is preferred over a master-key system.
Designed as a standard keyed-different brass padlock compatible with common hasps, chains, and lockout devices that accept a 1/4-inch shackle diameter and a body width of 1-9/16 inches.
Installation requires no special tools beyond proper hasp or anchor hardware sized for the 1/4-inch shackle. Always de-energize or lock out the equipment being secured before attaching the padlock, following applicable OSHA lockout/tagout procedures. Verify hasp slot clearance against the shackle dimensions before installation to ensure a proper fit.
