Key benefits and features - Unique numbering with identical keys: Each lock uses the same key cylinder and up to 260,000 possible numbers. This design keeps each lock uniquely identified while ensuring the key works across all locks. - Two keys per lock for convenience and security: Every lock ships with two keys—one for immediate use and one personal backup. With five locks, all sharing identical keys, you receive ten identical keys in total for easy management. - Safe and controlled key removal: The lock cylinder is designed so you cannot remove the key until the power source is isolated and locked, helping enforce proper lockout procedures. - Clear safety labeling: Includes a DANGER: Locked Out Do Not Remove label to communicate safety status and prevent accidental override or removal. Specifications and compatibility - Lock configuration: Five locks with identical key cylinders and identical keys across all locks. - Numbering: Each lock carries a unique identifying number from a pool of up to 260,000 possible numbers. - Key setup: Two keys supplied per lock (use key and personal backup key); total of ten identical keys for the five locks. Practical use scenarios - Electrical and mechanical lockout applications: Use the five identically keyed locks to concurrently secure multiple energy sources or control blocks during maintenance, ensuring all points remain safely isolated. - Facility maintenance and equipment service: On a large machine or panel network, technicians can lock out several components with a single key set, simplifying key control while maintaining safety. - Construction site or contractor operations: Teams can distribute a uniform key set to authorized personnel, enabling coordinated access control across multiple equipment points without juggling different key types. Performance and safety advantages - Streamlined key management: Identical keys across multiple locks reduce the need to carry and manage different key sets, while preserving individual lock identification through unique numbers. - Enhanced safety protocol support: The controlled key removal mechanism supports standard lockout procedures by requiring power isolation before any key can be removed. - Immediate visual safety cue: The included DANGER label provides a visible warning to suppress unauthorized removal and reinforce safety practices on site. Notes - This description preserves the stated features: identical key cylinders with unique lock numbers, two keys per lock, five locks with identical keys (ten keys total), a safety oriented lock design, and the DANGER: Locked Out Do Not Remove labeling.
