Heavy Duty Box

Measurements Explained

Unless otherwise specified all dimensions are expressed
as internal dimensions in mm as follows:
Length (L) = the longer dimension at the opening
Breadth (B) = the shorter dimension at the opening
Height (H) = the dimension from the top of the opening to the base

The dimensions L, B, H are specified in each description of the case construction, for some models the numerical value of B can exceed the numerical value of L.

Dimensions should be measured under standard climatic conditions, on the flat blank from the centre of crease bearing the thickness of the material in mind.

For telescope-type boxes:
The height (h) of the upper part (lid) should be given as a fourth measurement after an oblique stroke.
Example: 355 x 205 x 120/40 mm
(L) x (B) x (H)/(h)mm

For cases with overlapping outer flaps:
The length of the area of overlapping (o) should be given as a fourth measurement after an oblique stroke.
Example: 355 x 205 x 120/40 mm
(L) x (B) x (H)/(o)mm

Each design style includes one of the following indications:
M = usually manual erection A = usually automated erection
M/A = can be either manual or automated
M+A = requires a combination of both
