The case is fitted with interlocking aluminium sections to the joint
edges to give a splash proof seal. Edges are fitted with 30 mm aluminium
angle riveted every 100 mm. Large zinc coated pressed steel ball
corners and edge brackets will increase strength and protection. The
lids are secured to the case with butterfly type catchese. Recessed
sprung handles are fitted as shown.
