The number of compartments and/or pockets provided in the design of the tool container (with the exception of organizers, including those built into the lid — for them the number of cells is indicated separately, see below).
The more compartments or pockets, the easier it is to keep numerous items in the container at the same time. On the other hand, more compartments (for the same product size) usually means smaller individual compartments. The most modest models have
up to 10 compartments / pockets, in the most capacious this number can
exceed 30. Of course, when choosing by this parameter, you should take into account the type of container (see above). So, for traditional boxes, the maximum value is actually
20 compartments, and among backpacks there are models with
20 – 30 compartments.
Possibility
to change the size of the compartments provided in the tool box. This function is mainly used in
organizers(see "Type"). Usually, the partitions in such products (all, or at least most) can be removed and rearranged, thus adjusting the size, number and even shape of the compartments — for example, to provide enough space for a relatively large tool like a screwdriver or pliers. Another option is
bags and
backpacks(see ibid.), in which individual compartments can grow and shrink through the use of zippers or zip ties. Here the meaning of this function is somewhat different: it is aimed at optimizing the use of internal space depending on the amount of content. For example, if there is little content, a bag or backpack can be “squeezed” so that things do not hang around the cabin; and when an additional load appears, loosen the ties or unzip, providing the necessary volume.
