2-part ABS plastic inserts make up this cable tidy. They enable the tidy ducting of cables for computer, telephone or audio, through the surface of things like desktops, cabinets, shelving units etc. The two inserts, 60mm & 80mm have a spring loaded swivel cover plate. The cover plates can be removed for plugs to pass through.
The rectangle insert has 4 cable apertures & a ribbon slot.
