• The Wallis light duty earth inspection housing has a maximum safe working load of 2,000 kilograms. It is UV stabilised against degradation by sunlight and non-brittle to prevent cold weather damage.
• The unique, detachable easy-locking lid ensures security of equipment as the locking mechanism can only be operated by the special key provided with the housing. The base has built-in slots for locating earth bars.
• Its lightweight feature allows easy handling, storage and transportation. The termination depth is increased 100%by simply locking two units together, allowing deeper earth electrode connections to be made.
• Polypropylene.

The Wallis concrete inspection pits are load rated to 4,500kg and are suitable for most types of earthing and lightning protection installations.

• Lids are available in 2 types, 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, shopping arcades, supermarket forecourts, Mosques and cinemas where trip hazards are a potential problem.
• The base is designed to accept a diagonal earth bar with 5 or 7 terminations (EBC05 and EBC07).
• If an alternative high load inspection pit is required the Heavy Duty Inspection Pit (EPP001W) is recommended. Ideal for areas where high loads or small wheel vehicles are used, rated up to 6,000kg, lockable and available in black or grey.
