  • Tool holder assembly
    Patent number: 6920986
    Abstract: A tool holder assembly comprising two opposite end members spaced from each other. Two opposite rail members extend between the end members and are spaced from each other. A tool support arrangement is mountable between the rail members. The tool support arrangement has two opposite tracks spaced from each other, and upper and lower plates extending one above the other at different heights between the tracks. At least one of the plates is removably mounted between the tracks. The plates are adapted to have respective alignable holes for bi-level tool support. A mounting arrangement is provided for mounting the tool support arrangement between the rail members.
