1. A contacting device subassembly for the countercurrent contacting of a solid and liquid phase or a liquid and vapor phase, said contacting device subassembly comprising:
a first grid formed of a first set of spaced-apart and parallel-extending deflector blades;
a second grid formed of a second set of spaced-apart and parallel-extending deflector blades that are interleaved with and cross the first set of deflector blades at a preselected angle, the deflector blades in the first and second sets of deflector blades each having opposed ends and side edges, wherein the side edges of the deflectors blades in the first grid face the side edges of adjacent deflector blades in the first grid and the side edges of the deflectors blades in the second grid face the side edges of adjacent deflector blades in the second grid; and
first transverse strips formed by uncut portions of the side edges of adjacent ones of the deflector blades in the first and second sets of deflector blades and located adjacent each of the opposed ends,
wherein the deflector blades of the first and/or second sets of deflector blades include apertures and directional tabs associated with the apertures.
