The Weight Drop TBI apparatus generally consists of two main parts: the U-shaped Plexiglas box and a collection sponge.

The typical weight drop mTBI equipment consists of a U-shaped Plexiglas stand, a plastic guide tube, brass weights, a clamp stand, a fishing line, and a collection sponge. The lightly anesthetized rodent is placed supine on a scored tin foil with its head directly in the pathway of the falling weight.
