UNION 3104 Brass Open Shackle Padlock

The UNION 3104 Brass Open Shackle Padlock is a highly durable, UK-manufactured security solution designed for general-purpose use. Featuring a solid polished brass body and a robust manganese bronze shackle, this padlock offers exceptional corrosion resistance, making it particularly well-suited for outdoor applications and harsh environments. The non-sparking properties of the bronze shackle also make it an ideal choice for use in potentially hazardous or sparking environments.

Equipped with a reliable 4-pin tumbler cylinder mechanism, the 3104 provides dependable security. It utilizes a convenient snap-locking design where the key is required to unlock, but the spring-loaded shackle can be snapped shut without the key in place. For added convenience, the shackle remains retained inside the body when the padlock is open.

This padlock is supplied keyed to differ as standard with two nickel silver keys. For larger security setups, it can also be keyed alike or master-keyed upon request as a special order. Backed by a 5-year manufacturer's guarantee, the UNION 3104 represents a trusted, long-lasting choice for securing gates, lockers, sheds, and more.
