Double Barrel
by mozkomor
Double Barrel lets two barrels placed side by side join into one storage block, the same way vanilla double chests merge.
What it does
Two barrels set next to each other, end to end, horizontally or vertically standing upright, connect automatically into a single container. The merged pair uses a long oval lid texture so it reads as one large barrel. The placement rules follow the vanilla chest merging behavior, so the mechanic will be familiar to anyone who has built double chests.
Double Barrel is a Storage mod that gives barrels the double-container behavior chests have always had. Players who build large storage rows with barrels can now double the capacity of each unit without changing their layout. The server and every player need the mod installed. It requires Fabric API on both loaders, and it is published for Fabric and NeoForge under the MIT License, though the code is not open source. Files exist for 1.21.1 only, with 1.0.1 as the latest build on each loader, dated 2026-07-25.
Key features
Automatic barrel pairing
Two barrels placed side by side connect on their own, with no command or extra block needed.
Horizontal and vertical merging
Barrels join end to end on the flat plane and when standing upright, matching the chest layout.
Double barrel lid texture
A long oval lid texture makes the merged pair look like one big barrel rather than two separate blocks.
Vanilla-style merge rules
Placement follows the same rules vanilla chests use, so double barrels behave as expected for players.

Who it’s for: Players and server owners who use barrels for storage and want them to merge like double chests do. The mod adds no new recipes or items beyond the merged barrel behavior.
How it compares
Metal Barrels is another Fabric and NeoForge storage mod for 1.21.1, published under the MIT License and not open source, and it runs on client and server like Double Barrel. Stone x Iron Chests is open source under the GNU General Public License v3.0 or later and covers 1.21.1 – 1.21.4 on NeoForge only, so it does not offer Fabric files. Packed Chest is a Fabric-only open source mod under the MIT License for 1.21.9 – 1.21.10, which is a different version range from Double Barrel.
