National Highways Cabinet Pedestal Standoff Base

The NH600 Cabinet Standoff Base or Pedestals fit under the NH600C and aid in the passage of cables into the cabinet while preventing moisture ingress and gas build-up from the ground. Two Pedestal types are available, for use on a Chamber or for use on a Plinth. Pedestals for Plinths are made to fit on Extended 610 Plinth (which needs to be sourced separately). Pedestals for Chambers fit inside underground chambers that are 900 x 600 mm internal dimensions.

The Cabinet Pedestal Standoff Base Type 600C fit under the NH600C and aid in the passage of cables into the cabinet while preventing moisture ingress and gas build-up from the ground.

The NH600C Pedestals feature access panels on the front and back allowing access to the cables, gland plates for the passage of cables and vents to prevent gas build-up. The NH600C is designed, manufactured, and tested according to the National Highways (also known as Highways England) TR 2638 specification.

Both models of Pedestal come with M16 fixings, perimeter seal for NH600C and three removable sealing gland plates.
