Safety is the top priority when users are working on live parts. With the tool set including single open-end spanner and adjustable spanner, electricians and electrical specialists are ideally equipped for work on electrical systems. With 15° jaw positioning, the insulated single open-end spanners are perfect for the installation of terminals and sleeves in restricted spaces. The adjustable spanner provided is fully adjustable and has a maximum opening width of 30 mm. Damage to sensitive surfaces is minimised thanks to extremely smooth, parallel-acting jaws. Each tool in the set is subject to an individual piece test as per the international IEC 60900 standard, allowing users to work safely on live parts up to 1,000 V AC.
