Review: Security and peace of mind for my trailer - I purchased these a year and a half ago for my enclosed trailer doors and I'm thoroughly impressed with its performance. They are perfect for securing multiple areas, and the shrouded design adds an extra layer of protection against bolt cutters. The stainless steel construction ensures durability and resistance to corrosion, making it ideal for both indoor and outdoor use. The locks feel robust and well-made, providing a sense of security that’s hard to beat. The body is substantial, and the locking mechanism operates smoothly without any hitches. One of the standout features is fact that it retains the key when unlocked which ensures that it cannot be left unlocked. This is a great safety feature, especially for high-security needs. Overall, these locks offer excellent value for money, combining strength, reliability, and convenience. I highly recommend them for anyone in need of a reliable locking solution.
