Abstract
A pendant suspension system provides a continuously adjustable cable suspension system for luminaires. The cable suspension system has twin suspension assemblies, each comprising a cable held at both ends by a track adapter so as to form a downwardly depending loop. A luminaire is affixed on each end to the suspension system at the loop. The vertical height of the luminaire can be adjusted by pulling one end of the cable through the track adapter. Further, the luminaire can be connected to the loop through a rotation housing that permits rotational adjustment of the luminaire. Thus, the combination suspension system and rotation housing permits continuous vertical and rotational adjustment of an attached luminaire.
