case is made from 7mm Astroboard, a lightweight but very strong
polypropylene honeycomb material. The case is fitted with interlocking
aluminium sections to the joint edges to give a splash proof seal. Edges
will be fitted with 22 mm aluminium angle. Zinc coated pressed steel
ball corners and edge brackets will increase strength and protection.
The lid is secured to the base with two butterfly type catches at the
front and with two hinges at the back. A recessed sprung
handle will be fitted to the front. Internally the case has a basic 3mm
black carpet lining. Internal measurements are W850 x D400 x H200mm.
