A conveyor guide track (10) for conveying facade elements, comprising an open-ended rectangular profile having an upper surface (11) and an oppositely disposed lower surface (12) having an slot (13) extending in the longitudinal direction of the rectangular profile (10) is provided. The upper (11) and lower (12) surfaces are joined at their longitudinal extending edges to a pair of side walls (14), wherein the upper surface (11), the lower surface (12) and the pair of side walls (14a, 14b) together from a longitudinal cavity within the profile suitable for slidably receiving a facade attachment trolley member also extending through the slot (13). The conveyor guide track (10) also comprises at least one attachment unit (15) for connecting the conveyor guide track (10) to a corresponding attachment unit (15) of another conveyor guide track, provided at each longitudinal end of the profile. Each attachment unit (15) of the conveyor guide track (10) is positioned transversally within the boundaries of the side walls (14a, 14b), thus forming a flat exterior side surface along the entire longitudinal extension of the profile and along at least one sidewall (14b) of the profile. A method (30) for connecting at least two such conveyor guide tracks (10) is also provided.
