Heavy Chain - jaquadro/GardenCollection GitHub Wiki

Heavy chain normally spans one block in height and does not care what blocks are placed above or below it. It will make special consideration for wood post and lattice blocks, and extend upwards or downwards to fully connect to those surfaces when placed above or below.

Alternate Crafting

Rusty heavy chain can be created by taking iron heavy chain and "activating" it on a filled cauldron. The water will quickly rust the exposed metal.
