The workshop trolley insert from BGS comes as a 13-piece set. Made from chrome vanadium steel, the set includes six open-end wrenches and a special brake line wrench, both featuring a matte chrome finish. Additionally, there are six slotted special socket inserts that are compatible with a 10 mm square drive. The tools are specifically designed for versatile use, including the installation of temperature sensors, thermal switches, and handling bolted, angled piping. Stored in the appropriate workshop insert, the tools fit into all common tool trolleys.
