The Wallis concrete earth inspection pits are load rated to 4,500kg, which makes these earth pits suitable for most types of earthing and lightning protection installations.
There are two different types of lids that can be purchased with the concrete earth inspection unit. One with a central lifting eye for industrial applications. The other with a unique plain lid non-trip surface, ideal for public and pedestrian areas such as shopping arcades, supermarket forecourts, Mosques, cinemas etc. wherever trip hazards are a potential problem.
The base is designed to accept a diagonal earth bar with 5 or 7 terminations (EBC05 and EBC07). These are used when multiple connections to the earth rod are required.
If an alternative high load inspection earth pit is required, the Heavy-Duty Inspection Pit (EPP001W) is recommended as this product is ideal for areas where high loads or small wheel vehicles are used, rated up to 6,000kg, lockable and available with a black or grey lid.
