If you need to test cables less than 5" long, remove one CB board from the fixture and electrically reconnect it using this 64-conductor extension cable. You may then position the free-floating CB board as close to the 2nd CB board as necessary to accommodate short test cables (see photo below). Standard length is 12". Custom lengths available. Orders for custom lengths are Non-Returnable (NR) and Non-Cancellable (NC).
