Gravity locks are merely an advancement on a very basic concept. Essentially a gravity lock equipment can be placed on any object that can be opened, from boxes and vehicle doors to mecha cockpits, in order to seal the object closed. The gravity lock generates an intense gravity-based attraction between the two halves of the gravity lock, making it virtually impossible to open the object without the numeric code sequence used to unto its gravitational pull. A gravity lock has a hardness of 30, 300 hit points, and a break DC of 50.

The base Disable Device DC for a gravity lock is 35. The DC can be improved by adding +1 to the purchase DC per +5 to the Disable DC (Max 50).
