As the bell in its hanging from ceiling state has a 2x2 top, it should be able to be placed on the bottom of any solid block whose base is flush with the bottom of a block and has at least a 2x2 area on the bottom. However, this does not actually happen, and placement completely refuses. However, lanterns can be placed on the bottom of all of these blocks, while having a chain that takes up a 2x2 area.

Affected blocks (many more blocks in invalid positions may also be affected):

• Fences
• Walls
• Glass panes
• Iron bars
• End rods, when facing up or down
• Hoppers, when facing down
• Chests
• Grindstones, when facing down
• Brewing stands
• Flower pots
• Heads
• Chains
