The Sealey AK63172 is an 18-piece VDE insulated open end spanner set designed specifically for safe working on live electrical systems. Manufactured from hardened and tempered Chrome Vanadium steel, each spanner in this comprehensive set is fully insulated to VDE and EN 60900 standards, providing certified protection against electric shocks up to 1500V DC and 1000V AC. This professional spanner set covers sizes from 7mm to 24mm, offering a complete range for most applications encountered by electricians and automotive technicians. The full insulation on each spanner makes this set particularly valuable for technicians working on modern hybrid and electric vehicles, where 1500V DC systems are increasingly common and require specialist tools for safe live working.
