ChestSignLocker

Protect your chests with a simple sign. No commands, no complex setup — just place a wall sign on any chest and it's locked to you instantly.

How to use

Place any wall sign on a chest. It will automatically display [Protected] with your name, and no other player will be able to open it, break it, or steal from it using hoppers.

To remove the protection, simply break the sign or the chest yourself.
