Testimonial
I Wish All My Purchases Were Of This Quality.
I purchased a combination Master Lock in September, 1960, for use in middle school gym. Since then, it served me through high school and college, was the lock on my bike chain for years, including a 3,800 mile ride in 1976, and secures my locker at our fitness center. Most recently, it protected a spare tire on our van during an 8,300-mile trip to Alaska. After 64+ years of service with exposure to the elements it still works flawlessly. I wish all my purchases were of this quality.
