The BOTT system also has a selection of different sized shelves to secure intricate or small items. Of course the disadvantage of shelves is that people can often just throw anything on a shelf. Our shelves are routed out to the shape of the tool or part so it is obvious where it belongs. This is great for companies who use TPM and 5's, with these shelves and our tool boards you can instantly see if tools are missing. The shelf inserts are layered so that they can have finger holes and can accommodate lots of different shapes and sizes. The shelves 'clip on' to the BOTT standard perfo system.
