The Master Lock Cable Lock is a versatile option for securing bicycles, ATVs, grills, and lawn mowers both indoors and outdoors. It features a 6-foot long, braided steel cable that offers strength and flexibility, with a vinyl coating to prevent scratches and resist rust. The patented adjustable locking mechanism allows you to secure the cable tightly at any length from 6 inches to 6 feet, adding to its versatility.

Additionally, the lock employs a 4-dial combination, eliminating the need for keys and providing resettable security. The cable’s 5/16-inch diameter and dimensions (8 x 5.8 x 1.1 inches) make it relatively lightweight and easy to handle. However, while the braided steel construction offers decent security, it may not be as robust as other high-security locks, making it more suitable for low to moderate-risk areas.
