Key benefits and features - Structo-Cast non-conductive frame: tough, non-corrosive, and will not scratch fine wood or painted surfaces. The magnetic edge grips ferrous metal surfaces for fast, hands-free setup. - Robust construction: impact-resistant acrylic vials built to endure field use. Three easy-read vials provide quick reference for plumb, level, and 45-degree angles. - Easy to service: Quik-Change replaceable vial covers allow rapid vial replacement or maintenance at the job site. - V-groove frame for fast plumbing tasks: the V-groove design easily fits on pipes and conduit, delivering a faster, more stable reading on typical plumbing and conduit installations. What you gain - Safe for finished surfaces: non-conductive, non-scratching frame protects delicate woodwork and painted finishes during layout and installation. - Versatile mounting and reading: magnetic edge enables quick positioning on ferrous workpieces; three vials cover common alignment checks without swapping tools. - Low-maintenance, field-ready: replaceable covers mean you stay productive with minimal downtime. Specifications in brief - Frame: Structo-Cast, non-conductive, non-corrosive - Surface interaction: magnetic edge for ferrous metal surfaces - Vials: acrylic, impact-resistant - Vial configuration: three easy-read vials for plumb, level, and 45 degrees - Vial covers: Quik-Change replaceable - Frame design: V-groove to fit pipe and conduit Use scenarios - Plumbing installations: align and level pipe runs and conduit quickly. The V-groove fits around pipe, while the three vials provide plumb, level, and 45-degree checks to speed alignment and reduce rework. - Metal-framed or steel work centers: hold the level against ferrous surfaces with the magnetic edge for upright installations, brackets, or mounting rails, enabling hands-free setup and faster reads. - Fine-wood or finished surfaces: work on cabinets, shelves, or trim where the non-conductive, non-scratching Structo-Cast frame minimizes risk to delicate finishes while you verify level and plumb.
