Modular Kit ITA-179-A is a lockable molded plastic attaché case. It contains one fiberglass reinforced plastic board the same length and width as the interior dimensions of the attaché case covered on both sides with Velcro loop cloth . There are sixteen removable items, each one backed by Velcro hook tape. In a training or test situation, every item can be used alone or in combination and can be inserted into another piece of luggage. The items can be assembled together to build an inert IED, or they can be used individually, to be hidden in difficult areas in luggage - such as in corners, under dense items, and along structural frame elements.

It contains x-ray correct representations of a dynamite cartridge, sheet explosive and a demolition block, all inert; 8 electric detonators (blasting caps) with bridgewire assemblies, an electronic countdown timer and a mechanical (windup) timer, a 9 volt battery and two size AA batteries in a battery pack.  It also has two lengths of insulated hookup wire. Everything has Velcro hook tape on it, and the items are attached to a Velcro loop surface cloth sheet on a thin board. This allows for the user to easily transport, store and find the items in the carrying case.  The user can assemble several types of IEDs from the components.  The items can be individually inserted into the luggage to train and test the security screener to detect explosives and bomb making components.
