The Tolsen 15122 is a 1/4" drive extension bar from the Industrial line, designed to help you reach tight or deep spots where a standard ratchet cannot fit. Crafted from chrome vanadium steel, this tool provides the necessary strength and durability for demanding mechanical work, while its satin finish helps reduce glare and improves grip during use. Measuring 100mm in length, this compact extension is a practical addition for anyone performing precision repairs on engines or small machinery, as it allows for a more flexible range of motion without adding excessive bulk to your toolkit.
