Shift Double CHEST
by ItzRealAqab
Shift Double CHEST changes how chests join: placing one next to an existing chest while holding Shift merges the two into a double chest.
What it does
Normally two chests join into a double chest only when they are placed side by side in the usual way. This Fabric mod adds a Shift-based control on top of that: sneaking while placing a chest next to another one merges them automatically, so a player can set up a large storage row without extra steps. The mod gives precise control over chest placement and the interactions that follow it.
Only the server needs the mod, so players join without installing it. It is built for modern Fabric versions and aims to avoid unnecessary server overhead. Fabric API is required and must be installed alongside Shift Double CHEST. Files are published for game versions 1.21.11 and 26.2, and the latest file is 26.2, released 2026-07-21. The mod is released under a custom license and is not open source.
Key features
Shift-to-merge control
Holding Shift while placing a chest beside an existing chest merges the two into a double chest.
Automatic double chests
Placing a chest next to another chest while sneaking forms the double chest without a separate action.
Precise placement
Chest placement follows the sneaking input, so ordinary placement keeps working for players who do not hold Shift.
Lightweight design
The code is kept light for modern Fabric versions, so it adds little work on the server.

Use cases
Building storage rows
Players who line up many chests can merge each pair in one placement, which keeps a storage room tidy.
Modded server storage
Server owners can add the behavior without asking players to install anything on their side.
Who it’s for: Players and server owners on Fabric who place many chests and want a quicker way to make double chests. The mod matters most where chest layout is part of the build.
How it compares
ChestFill+ is a Fabric mod for 1.21.1 – 26.3 that runs client-side only and is released under All rights reserved. Double Ender Chest, the Fabric build for 26.2 – 26.3, is open source under the GNU Lesser General Public License v2.1 only and needs the client and server. Shift Double CHEST covers game versions 1.21.11 – 26.2, is server-side only and uses a custom license that is not open source, so it changes only what the server does with chests.
