1. An attachment unit for attachment to an assembled modular conveyor belt, the attachment unit defining:
a longitudinal direction;
a first transverse direction being perpendicular to the longitudinal direction;
a second transverse direction being perpendicular to each of the longitudinal direction and the first transverse direction;
the attachment unit comprising:
a flight part for slowing down or blocking an element, wherein the flight part extends along the longitudinal direction; and
an attachment part comprising:
a first row of protrusions being parallel to the longitudinal direction,
wherein the first row of protrusions comprises a plurality of protrusions; and
a second row of protrusions being parallel to the longitudinal direction,
wherein the second set of protrusions comprises one or more protrusions,
wherein each of the protrusions extends away from the flight part in the first transverse direction,
wherein each of the protrusions is a member of a pair of protrusions, the pair of protrusions comprising a protrusion from each of the first row of protrusions and the second row of protrusions,
wherein the protrusions within said pair of protrusions are separated in the longitudinal direction, and are nearest neighbors in the longitudinal direction,
wherein each protrusion within the pair of protrusions comprises a protuberance extending in the longitudinal direction toward the other protuberance within the pair of protrusions, wherein each protuberance is configured to engage with a recess of the modular conveyor belt, and
wherein the first row of protrusions is off-set along the second transverse direction such that there is a gap between the first row of protrusions and the second row of protrusions, wherein said gap extends in the second transverse direction.
