The Kramer T1AF-44 Inner Frame for TBUS-1Axl Bus neatly covers your Kramer table-mounted bus enclosure, leaving room for the power outlets and cable-through ports that correspond to your specific needs. The T1AF-44 is configured with two double power-socket slots and four insert slots (two blind and two with cable-through holes). You can rearrange or remove any of the plates mounted on the inner frame and replace them with different Kramer passive wall plates or connector modules for interfacing A/V type signals.
