【Complete Security Solution】This 5-pack of retractable cable locks provides a comprehensive security system for your valuable electronics. Each lock in the package is keyed alike, meaning all 5 locks can be opened with the same set of keys—no need to manage multiple keys for different devices. The included keys are uniquely numbered for easy identification and replacement if needed. 【High-Quality Self-Rolling Cable】Featuring a durable self-rolling cable design, this lock offers maximum convenience and portability. The cable extends up to 2400mm (8 feet) when fully stretched, providing ample length to secure various devices. It automatically retracts when not in use, keeping it compact and tangle-free for easy storage and transport. Made with robust materials, it has a military-grade build that ensures long-lasting performance without taking up extra space. 【Versatile Application】Designed for universal compatibility, this lock works seamlessly with a wide range of electronic devices: - For notebooks, monitors, and desktop computers equipped with standard 3x7mm security keyholes: Simply insert the lock head directly into the keyhole—no additional accessories required. - For laptops, tablets, smartphones, and other devices without built-in keyholes: Use the included anchor plate for secure attachment. The anchor plate features strong adhesive backing; ensure the surface is clean before application, apply static pressure for 3-5 minutes, and allow it to cure for up to 48 hours to achieve maximum holding strength of up to 60 pounds. 【Enhanced Durability and Safety】Engineered for reliability, the cable connector has been tested to withstand tensile forces up to 1100N (approximately 247 pounds), ensuring your devices remain securely locked in place. The adhesive on the anchor plate provides a firm grip on smooth surfaces when properly installed. This combination of features makes it an ideal choice for protecting electronics in homes, offices, schools, or public spaces. 【Easy Setup and Use】Setting up this security lock is straightforward: 1. For devices with keyholes: Insert the lock head into the slot and turn the key to lock. 2. For devices without keyholes: Clean the intended area thoroughly before attaching the anchor plate as described above; once set, connect the cable through an available opening or around a sturdy part of the device. The intuitive design allows quick locking and unlocking while maintaining high security levels.
