Each LK4 provides a means of permanently labeling the four I/O channels on C4m and C4o cards when they are installed in an F6 as part of an AllFrame Multi-Modular I/O System.

Print custom label text with any desktop printer. The included clear plastic cover keeps the text clean and smudge free, and allows the label strip to be updated in the future if needed. 

Note that the LK4 is not compatible with the C4dio card for AllFrame.
