Larsen-Loc® Door Locking System

The Larsen-Loc® Door Locking System, introduced by Larsen's in 1997, revolutionized the industry by providing a modern and innovative approach to securing cabinet doors equipped with cylinder locks. Unlike traditional methods that required breaking glass to access the contents of the cabinet, the Larsen-Loc® system ensures locked cabinets can be accessed without damaging the glazing.  All Larsen's cabinet loacks are keyed alike for easy access during inspections.

Key features and advantages of the Larsen-Loc® system include:

Independence from Glazing: Larsen-Loc® allows for locked cabinet access without the need to break glass, making it suitable for various door styles and glazing options.

Tamper Deterrent: The steel cam lock-based design provides a high level of security, deterring tampering and unauthorized access.

Emergency Access: During emergencies, the cabinet door can be opened quickly by pulling firmly on the handle, saving critical seconds compared to systems that require breaking glass first.

Clear Instructions: The factory-applied lettering on the cabinet reads "IN CASE OF FIRE ONLY - PULL FIRMLY ON HANDLE," providing clear guidance for emergency situations.

Safety: Eliminates the need for traditional glass breaker bars, reducing the risk of injury from broken glass or the use of unsafe substitutes like hands or shoes.

Cost-Effective: By eliminating the need for other glass-breaking methods, Larsen-Loc® offers a cost-effective solution for securing cabinet contents.

Overall, Larsen-Loc® represents a significant advancement in cabinet locking systems, prioritizing safety, security, and ease of access during emergencies without compromising on design or flexibility.
