This is a thin and lightweight wide-opening monkey wrench from TOP (Top Kogyo), a tool manufacturer that Japan is proud of. Product Features: Maximum jaw opening of 42mm: Opens much wider than a standard monkey wrench, making it ideal for plumbing and large diameter nuts (up to M27). Lightweight design: Despite its compact size (approximately 200mm in length), it has a large jaw opening, making it very useful for working in tight spaces and for carrying around. Minimal play: As expected from a Japanese-made product, it's built solidly. ■ Product Condition Used for work and DIY projects, so there are rust, scratches, and signs of use overall. The adjuster (screw part) moves smoothly, and there are no practical problems. Please check the condition in the photos. ■ Specifications Manufacturer: TOP (Top Kogyo) Model Number: HY-42 Jaw Opening: 0-42mm Made in Japan Notes (Profile/Shipping): Condition: Due to being a used and stored item, there are scratches, dirt, and rust.
