Lightning Protection

The Wallis interface clamp, sometimes referred to as the ‘coffin clamp’, is very adaptable and can be utilised to connect conductors in a variety of different sizes and in a variety of configurations. This item can also be used for connecting flat tape to 8mm or 10mm solid circular conductor, or flat tape to 70sqmm cable. This is ideal where the lightning protection system has been designed in 8mm copper conductor but the connection to the earth rod is made using 25 x 3mm copper tape. These interface test clamps will also serve for making through joints and tee connections in 8mm solid circular conductor, flat tape or cable.
