Relative movement between the center link (10) and trolley brackets is restricted by a pair of bosses (28) formed on the sides (20) of the center link and projecting inwardly into the open central portion medially between the ends of the center link. Complimentary shaped recesses (50) on the bases (32) of the pair of trolley brackets are positioned in interlocking engagement with the pair of bosses by an attachment member (16) which is mounted between and is connected to the bases of the pair of trolley brackets. In an alternative construction, only an attachment member (66) extends through the open central portion of the center link and is provided with grooves (74) engaged by the pair of bosses (28).
