Adjustable design for versatile use: the belt includes two wrench sizes. The large wrench can adjust up to 150 mm (6 in) in diameter, while the small wrench can adjust up to 100 mm (4 in) in diameter. Durable material: made from rubber to provide long lasting performance and reliability. Practical function: the small wrench is especially useful for removing nuts, bolts, and caps that are difficult to loosen or remove. Flexible and adaptable: the belt can loosen and conform to a variety of shapes, offering flexibility during use. Key benefits at a glance: helps with fastener removal in tight or awkward spaces, supports a range of diameters, built to endure regular tool use, and reduces the effort required to reach challenging fasteners. Typical applications: Automotive and machinery maintenance where large or irregular fasteners are present and space is limited. Bicycle maintenance and home plumbing tasks involving nuts, bolts, or caps up to 100 mm in diameter. General DIY projects and repairs that involve irregular shapes or hard to reach fasteners.
