For installation, assembly and servicing work, users often require several different spanners. The adjustable spanner by Wiha reduces the time spent searching for the correct tool. With an opening width of up to 30 mm, it offers the perfect alternative to a standard spanner. Damage to sensitive surfaces is minimised thanks to extremely smooth, parallel-acting jaws. The insulated adjustable spanners undergo individual piece testing as per the international IEC 60900 standard, thus providing users with a tool to work safely on live parts up to 1,000 V AC.
