Abstract
A new and improved cable bushing including a frame portion, and a detachable filler portion connected to the frame portion, is herein disclosed and claimed. The filler portion includes at least one hinged flap movable between a first position in which the flap is remote from the interior of the frame portion, and a second position in which the flap is disclosed substantially within the frame portion so as to permit a cable to be received therethrough while the frame portion occupies an opening within a unit of office furniture or partition. The filler portion with its flap in its first position has a substantially flat top surface which may be disposed in a coplanar relation with the top or exposed surface of the structure in which the bushing is mounted.
