HEX makes the accessories that connect, support and test an earthing and lightning protection system, in copper alloy, brass, gunmetal, aluminium, stainless steel and nylon. The range includes clamps, rod, tape and pipe bonds, test clamps, air rod saddles and terminal bases, tape clips and conductor holders, earth bars and links, earth plates, copper tape, braids and conductors. For the earth rods, pit chambers and compounds, see the system components.
Copper alloy clamps have a body chosen for corrosion resistance. The A type fits a 12 mm rod. The B type connects a 5/8 inch rod to tape (26 × 12, 40 × 12 and 51 × 12 mm). The C type connects a rod to a cable (35 to 95 mm²). The D type connects a rod to a cable lug. Gunmetal versions are available. U-bolt rod to cable clamps cover conductors from 16 to 300 mm². Comb clamps (brass) take 6 to 8 mm and 9 to 12 mm round conductors, in accordance with IEC standards.
Tower, rain water pipe and watermain bonds connect conductors to steel structures and pipes. Flexible braid bonds are used on gates, doors and fences. Oblong, interface, screwdown and test bond clamps are available for copper conductors, with aluminium versions on request.
UL listed brass, bronze and zinc die cast ground clamps for direct burial, bare wire and armoured ground wire, and versions with threaded hubs for conduit pipe.
Aerial elevation rods (electrolytic copper, 15 mm, 500, 1,000 and 2,000 mm), multiple points, terminal bases (M16 or M20), saddles for ridges and flat surfaces, and side mounting rod brackets (75 mm projection from the wall).
Brass tape clips and DC tape clips for bare copper tape, roof and wall conductor holders to DIN 48826 B in stainless steel 304 and copper, and nylon 6 holders.
Earth bars and disconnecting links in 50 × 6 mm hard drawn copper to BS EN 13601 with 6 to 30 terminations, solid copper earth plates from 500 × 500 mm to 1,000 × 1,000 mm, lattice copper plates, and copper bonded steel plates.
Hard drawn copper bar to BS 2874, bare copper tape to BS 1432, flexible braids to BS 4109, solid circular conductors to BS 1433 (copper) and BS 2898 (aluminium), and stranded copper conductor to BS 6360 from 6 to 95 mm².
The rod to tape clamp (B type) and the rod to tape coupling.
The rod to cable clamp (C type) and the U-bolt rod to cable clamp. The rod to cable lug clamp (D type) is for a cable lug.
The earth boss provides an earth point on a steel structure. It has a mild steel body with stainless steel fittings, and it is welded into place. The catalogue lists one size (HPB-01), with a 10 mm hole thread and 50 × 50 mm body.
