The standard back support height for RS 60 cable trays is 60 mm.

Standard Back Support Details

For RS 60 cable tray systems, the rail height is 60 mm, which defines the vertical dimension of the tray and its back support structure . This height is consistent across tray widths ranging from 100 mm to 300 mm and applies to both ceiling and wall-mounted installations . The back of the TKS profile, which forms part of the support, must be stiffened with a spacer (TKSD 20) to ensure structural stability .

Support and Mounting Considerations

Cable tray supports are designed to handle the weight of cables and environmental loads. They can include cantilever brackets, pendant brackets, and ceiling suspensions, with threaded rods or adapters for secure attachment . The support spacing and placement are critical: supports should be installed close to joints (≤150 mm) and at intervals appropriate for the tray span and load . Proper installation ensures the tray maintains its height and alignment, preventing sagging or structural failure.

Compliance and Standards

The RS 60 system meets DIN 4102 Part 12 and other relevant standards, ensuring that the back support height and overall tray construction comply with safety and load-bearing requirements . For industrial or specialized installations, additional considerations such as load capacity, environmental exposure, and cable type may influence support design and height adjustments . In summary, for standard RS 60 cable trays, the back support height is 60 mm, and proper installation with stiffeners and appropriate brackets ensures compliance with safety and structural standards.
