Kramer's TS-PEU is a power extension unit that includes six universal power sockets: one on the surface of the unit and five hidden neatly under the table. TS-PEU fits into TBUS inner frame modules with dual power socket openings. To use the hidden sockets, simply pull TS-PEU out of the TBUS using the handles and lay it on the table. When not in use, carefully slide TS-PEU back into the TBUS.
