How does this mount to the truck?

The Tuffy underseat lockbox mounts to the truck using an innovative mounting system that is only accessed from inside the box. This makes it difficult for anyone to remove the box without knowing the combination and having access to the inside.

Can I remove this lockbox easily if I need the space?

Yes, the entire lockbox can be removed in seconds without the need for any tools. This is useful if you need to use the full floor space of your truck bed for larger items.

What kind of lock does this use?

This Tuffy lockbox uses a three-digit combination lock. The lock is part of Tuffy's Pry-Guard Locking System, which is designed to resist forced entry.
