A cable tray section includes first and second side rails, each side rail having opposite longitudinal ends and a length extending between the opposite longitudinal ends. A splice member is secured to one of the first and second rails adjacent one of the longitudinal ends. The splice member includes at least one opening configured to receive a fastener to connect the splice member to another splice member of another cable tray section to attach the two cable tray sections together. The at least one opening has an axis extending along the length of at least one of the first and second rails.
