The Union 310251 is a straightforward, no-nonsense padlock for anyone who needs something reliable and doesn't want to overthink it. The body is solid brass with a sanded finish, and it's paired with a 2" manganese bronze shackle that's spring-loaded, so it pops open on its own as soon as you turn the key. The shackle also stays retained in the body when the lock is open, which cuts down on the number of times a padlock ends up lost in the bottom of a toolbox or dropped in a yard.

It's a snap-locking padlock, meaning you can push it shut without a key, but you'll always need one to open it back up, handy for gates and cabinets that get opened and closed constantly through the day. The 5-pin tumbler mechanism gives a reasonable level of pick resistance for a general-use padlock, and Union supplies it with two nickel silver keys as standard, with the option to have it keyed alike or master-keyed if a site needs matching locks across several gates or cabinets.

This is the kind of padlock that turns up on a dozen different jobs around a warehouse, yard, or construction site, nothing fancy, just solid brass-and-bronze hardware that keeps doing its job with minimal fuss.
