The CORE-BULK Tri-Circle Padlock Iron Long Shackle is a 38mm security device designed to provide protection for a variety of applications. It features a long shackle design that allows for more versatile usage, such as locking gates, sheds, storage units, and more. The padlock itself appears to have a solid body construction with a self-colored finish that presents a darker, iron look while the shackle sports a golden tone, providing a contrast in color which could be an indication of different material or finish used for better durability against cutting and sawing attempts. The inclusion of keys signifies that it operates on a traditional key mechanism, ensuring reliable and straightforward security. This padlock is suitable for both indoor and outdoor environments where a longer shackle is necessary for locking through larger fittings or multiple items.
