Secure Doors Fast & Cost-Effectively
PRIME-LINE Door Knob Lock-Out Device is a security accessory designed to fit over round doorknobs, providing a physical barrier to prevent unauthorized access. Made from durable diecast metal, it features a removable cylinder retained by an O-ring for easy cleaning and maintenance. This device is suitable for various applications including rental properties, eviction procedures, home sales, and workplace security, offering a cost-effective alternative to lock replacement. Its universal fit accommodates doorknobs up to 2-7/16 inches in diameter with a 1-3/16 inch shaft opening, ensuring compatibility across many standard doors.

Ideal for temporary security needs, it supports rental management, eviction processes, and controlled access at job sites or storage rooms, reducing costs and downtime.
