Metal Window Bars were craftable, placeable items made out of Low Quality Metal. They could be placed in either Wood Windows and Metal Windows. Metal Window Bars were used to prevent players from climbing through windows. Players could fire both into and out of them. They also raised the toughness of Wood Windows as Wood Windows with Metal Window Bars required 2 Explosive Charges to destroy in instead of just 1.
Note: The bars themselves could not be destroyed, only the window frame itself could be destroyed.
