The Cabinet Pedestal Standoff Base fit under the National Highways Cabinets and aid in the passage of cables into the cabinet while preventing moisture ingress from the ground, from entering the Cabinet.
The Cabinet Pedestal Standoff Base feature two Pedestal types depending on how the cabinet will be installed: onto the corresponding plinth (Extended 610 Plinth – please source separately), or using an underground chamber. The NH Pedestals feature access panels on the front and back allowing access to the cables, gland plates for the passage of cables and ventilation below the sealed gland plates allows the release of moisture blown through the duct network and prevents it from entering the cabinet.
Pedestals are available for all NH Cabinets: NH640 Cabinet, NH600 Cabinet and NH609 N Cabinet, all available from Ritherdon. The NH Pedestal or Base is designed, manufactured, and tested according to the National Highways (also known as Highways England) TR 2638 specification.
National Highways enclosures are supplied without keys as standard. Please contact your Scheme Designer for further information and supply details.
