POWERFUL MAGNET FOR STRONG GRIP: The ARROW plumber level features 4 high-strength magnets, providing a secure grip of over 9.9lbs on iron surfaces. The rare-earth magnets also prevent the small bubble level from falling out, making measurements easier and more stable. MEASUREMENT ACCURACY: Equipped with dual accurate metric and SAE scales, this multi-functional level tool doubles as a ruler for versatile use. The 0°, 30°, 45° and 90° vials of the leveler provide maximum accuracy of 0.5/1000, ensuring reliable measurements for all your daily tasks and projects. ALUMINUM ALLOY FRAME: Crafted from high-quality aluminum alloy, this magnetic torpedo level is more durable and refined than plastic counterparts. Meanwhile, profiting from the oxide coating on the surface, this level has a certain degree of rust resistance, ensuring longevity even in harsh conditions. EASY-TO-READ VIALS: The spirit level features 4 high-visibility bubbles (0°/30°/45°/90°) and a top-view window, offering enhanced visibility. The yellow-green solution contrasts with clear bubbles sharply, while the top-view window makes it easy to read from both front and top angles. V-GROOVE DESIGNED: The V-groove of the 8-inch torpedo level ensures precise measurements on cylindrical surfaces like pipes or conduits. This shape offers stability and accuracy, making the level an essential tool. ARROW 8"Aluminum Conduit Level with Magnetic
