Copper Rod to Earth Tape ‘A’ Clamps

‘A’ clamps are earth clamps used for joining and clamping earth rods to different sizes of copper earth tape – the clamps are highly resistant to corrosion and mechanically strong offering a long life span and earth connection to both copperbond and solid copper type earth rods.

Most of the ‘A’ clamps are manufactured from aluminium bronze with M10 x 25mm phosphor bronze set screw (ERA1625 comes with a stainless steel grade 316 set screw).

The Wallis ERA1625A is made from aluminium with M10 x 25mm stainless steel set screw.

The aluminium version is mainly used for connecting aluminium earth tape to a puddle flange rod as part of a lightning protection system.
