Achieve perfectly level results on any project with this 4-piece box level set, featuring 10, 16, 24, and 48-inch levels to handle everything from tight spaces to long spans. Built with a thickened aluminum alloy frame and double-sided milled base, these levels resist bending, wear, and corrosion for long-lasting accuracy. Fluorescent, light-up bubble vials in acrylic glass provide clear readings at 45°, 90°, and 180°, even in dim work areas. The 10-inch level includes strong magnets for hands-free use on metal surfaces. An Abs and Tpe handle, metal anti-slip side pattern, and shock-proof construction enhance grip and durability, while the dust-sealed nylon storage bag keeps all four levels protected and organized for easy transport to any job site.
