Empire Industries MLBX48 Box Level 48 Inches

Product Description

The EMPIRE INDUSTRIES MLBX48 is a 48-inch box level designed for trade professionals who require consistent, reliable accuracy across plumb, level, and flat measurements. Built around an all-metal backbone frame, it delivers a rigid, long-lasting structure with reinforced vial retention. The magnified bubble vials provide high-contrast readability in low-light and demanding jobsite conditions. Amplified rare earth magnets are integrated into the frame for secure holding on ferrous surfaces. Accuracy is rated to 0.029 degrees (0.0005 inches per inch) and is backed by a lifetime accuracy guarantee. Licensed electricians, plumbers, HVAC installers, and general tradespeople rely on this tool for layout and installation work.

The MLBX48 is suited for residential and light commercial installation work. It fits naturally into tasks such as plumbing stack alignment, electrical panel layout, ductwork positioning, and structural framing checks. The 48-inch length spans studs, joists, and duct flanges with a single placement, reducing the need for multiple readings. High-density removable end caps protect the frame in tight spaces and allow access to confined areas. Wide, durable handles support single-hand carrying on busy job sites.

Installation Notes

No power disconnection is required for level use, but always follow applicable site safety protocols before climbing ladders or working in energized spaces. Keep the measuring surface clean and free of debris to preserve calibration accuracy. Do not use the level as a pry tool or strike surface, as impact damage can affect vial accuracy. Store horizontally or hang using the all-metal hang hole to maintain long-term calibration.
