Сompartments
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.
Organizer slots
The number of individual cells provided in the organizer. In this case, we can talk about an organizer as a separate device (see "Type"), or a set of cells built into the lid of the box (see "Lid with an organizer"). And for solutions with removable partitions, in which cells can be combined, the maximum number is indicated — with all installed partitions.
Organizers, by definition, are designed mainly for small things. Therefore, the more cells there are, the more varieties of small items can be stored in a container. For example, in 10 cells you can keep bolts of five different sizes and separately nuts for them. Such a number of compartments —
up to 10 — is generally considered small, but in fact it is often quite enough.
11 – 20 cells can be called an average, and the most capacious organizers have
up to 30 compartments. However it is worth considering that with the same dimensions of the container, an increase in the number of cells leads to a decrease in their volume.
Place for bits and sockets
The presence on the lid of the box (may occur in other versions, but very rarely) of separate
niches for bits and end heads. Something similar is implemented in tool kits, where each accessory has its place and clearly lies in it.
Lock material
The material from which the container locks are made. Most often we are talking about fasteners that close a case or drawer, but sometimes this information is indicated for fasteners in bags, backpacks, etc. The main materials for their manufacture are:
-
Plastic. Plastic is inexpensive, but in general it is inferior to metal in terms of strength and reliability. However, often these moments do not play a decisive role (or are compensated by design features - for example, the large thickness of individual parts).
-
Metal. Metal locks are very durable and reliable, but they are more expensive than plastic ones. Tool boxes and containers made of almost any material can be equipped with such locks.
—
Plastic with metal. This combination is not uncommon in the design of tool boxes and containers. As a rule, the locking bracket of the lock is made of metal, which bears the main load in the locking mechanism, and the “tongue” is made of plastic.
