Plugin Slot Lock

Slot Lock, Secure Inventory Slots

Slot Lock is a lightweight Bukkit plugin for Java Edition servers that forces a chosen item to remain in a specific inventory slot. It helps protect important equipment, tools, or custom items from accidental movement, swapping, or removal during gameplay.

Administrators can define locked items and slots, with support for item sub values, configurable command execution by the player or console, and permission based variations in later releases. Its archived builds target older Minecraft versions, mainly 1.6.2 through 1.8.1. We recommend Slot Lock for classic Minecraft server projects needing simple inventory control, while BoxToPlay provides a convenient server experience.
