When Jim Venkman was unable to convince the Ghostbusters to help him release and trap Hob Anagarak, he partnered with Dr. Bassingame. Bassingame agreed to specially design a Containment Fence to keep Hob confined and docile. The fence was design correlated to Bassingame's projected size of Hob, based on the block of black ice. However, once Hob grew to his normal height of 30 feet, the fence's electric shocks only annoyed him. Hob easily destroyed the fence with his flame breath.
