The Kappa provides a thin silhouette that angles on the inside to create a large storage compartment for wiring and equipment. The bases have vertical brushed aluminum trim on the ends and an open base area with access for wire management. When using three or more bases, the Kappa base should not be used as a center base. Specify Epsilon or Gamma as center bases when Kappa is used as outer bases. See the specific top size for the appropriate number of bases required. The Kappa base is designed to work with the Mediatrac rail system. When installed, the base mounts outside the rails providing clear access for the Mediatrac grommet system if specified.
