	A redstone comparator can be placed on the top of any block with a solid full-height top surface (including top-mode [[Minecraft:slab]]s and upside-down [[Minecraft:stairs]]). {{IN\|be}}, a comparator can also be placed on [[Minecraft:wall]]s and [[Minecraft:fence]]s. For more information about placement on non-full blocks, see [[Minecraft:Opacity/Placement]].
