The installation of cable tray elbows is generally more labor-intensive than straight tray sections due to alignment, support, and connection requirements. According to industry estimates, 90-degree horizontal and vertical elbows require additional man-hours compared to straight runs, often ranging from 0.5 to 1.5 hours per elbow, depending on tray size, material, and site conditions . Accessories like connector plates, expansion joints, and drop-outs may further increase labor time.
