There were the first models designed & manufactured completely in Structofoam & they have proven themselves to be the complete answer to engineering integrity. Structofoam is our unique material specification that has superb strength & impact resistance allowing machines to be truly rugged yet without a weight penalty. The rugged Structofoam container is mounted on 4x75mm (3”) non-marking, heavy duty castors & the compact size makes it ideal for numerous trades where it must frequently be moved from place to place such as builders, shop fitters, contractors etc.
