Faulty Prisoner Shackles is Clothing that is equipped in the Footwear slot. It has a Level 5 Lock and a Level 10 Strength, which is a lower level compared to the standard shackles. This item is part of the "slaver loot store" ITEM_PLACEMENT_GROUP which is not found in game, so it is impossible to obtain in an unmodded playthrough.
