Devil's trap (object)

A Devil's Trap is a means to trap a demon. It first appeared in its selt titled episode, Devil's Trap. Like Salt or Iron, Demons can't escape once inside the trap. They can easily walk into one, but can't get out unless the circle is broken.

Usage
Hunters need a roof or floor to draw this trap to catch a demon. They can use, chalk, spray paint, marker, or blood (Caged Heat) to draw it. Even using it as a light can be effective (Weekend At Bobby's). A Devil's Trap can also be conceled and still catch a demon. Once down, this can be used to trap any sort of demon.

In addition, it can be used to protect something. In Devil's Trap, Sam draws it on the truck of the Impala to protect the colt. Another situation is in All Hell Break Loose Pt.2, when Samuel Colt created one giant one to protect the Devil's Gate. This one was made out of pure iron railroads, so a demon couldn't break it.

Location Wise
Bobby has a Devil's Trap in his living room near the fireplace (which is used to trap Meg). He also has one outside the panic room, and two more inside the panic room itself (floor and fan).

One Weakness
Despite the fact that it can trap any kind of demon, it can also be broken by a demon. Powerful demons can easily break the trap by destroying the outside ring. As well as destroyed from inside the ring (Crowley did it in Caged Heat). Humans when threatened can also break the trap when threatened.
