The benefits of having properly organised tool storage and control include: • The red underlay gives instant recognition of a missing tool and the top layer of foam is durable for industrial use. • Finger cut-outs make tool retrieval very easy. This is extremely efficient as it eliminates the struggle of digging out the tools multiple times. • Rapid tool location for instant use. • Protection of expensive kit. • Prevention of tools sliding around during transit. • Avoids loss or theft of tools. • Easy to see if tools are not replaced. • Safety and peace of mind as tools will not be left within aircraft/vehicles/machinery
