Telect no longer offers the 405-2065-040, which was a 10x25 connectorized terminal block for MDF frames. The closest terminal block that would still be able to support a 10x25 installation is the 425-1066-040 which is a 12x25 connectorized terminal block. The 425-1066-040 can be used as a 10x25 block, if the last connector is not used.
