The Empire EM75.78 78 in. Magnetic Box Level is a long aluminum box beam level built for accurate layout and installation work. This is a box level designed for checking level and plumb over long spans in framing, door installation, steel stud work, and general construction. Model Number: EM75.78. If you need a level that can cover wider openings and longer runs without giving up accuracy, this is the kind of tool that earns its keep fast.

The big selling point here is accuracy paired with length. Empire rates it at 0.0005 in. per in. in all working positions, which is the kind of number that matters when you are setting doors, aligning framing members, checking long walls, or working across multiple studs. A 78 in. level gives you a better read over long surfaces than a short torpedo or 24 in. level, so you catch crowns, dips, and twist sooner instead of finding them later when trim, cabinets, or finishes start fighting you.

The frame is aluminum with a reinforced box beam design, and that matters because long levels take more abuse just from being hauled around the job. Empire also uses precision milled edges for guaranteed accuracy, so the reference surfaces are made to stay reliable when the level is laid against material. For a tool this length, frame stiffness is not just a nice extra. It is the difference between a dependable reading and a guess.

Empire built this level to be easier to read in real jobsite conditions. High impact acrylic e-Band block vials are paired with high contrast surrounds to make the bubble easier to pick up quickly. The 300 degree viewing window helps when your body position is awkward or the level is set high, low, or tight to surrounding material. That saves time because you spend less effort shifting around just to confirm the bubble.

On the practical side, the rare earth magnets are a real benefit if you work around steel. They let the level hang onto metal studs, pipe, and door frames so one hand can stay free for positioning or fastening. Surface grippers help keep the tool from sliding on flat or angled surfaces, and the grip zones make a long level easier to carry and reposition. Removable shock-absorbing end caps protect the frame during transport and can be removed for scribing when you need to mark long straight lines cleanly.

This Empire level is a strong fit for contractors, remodelers, carpenters, metal stud framers, door and window installers, and serious DIY users who want better control over long-span layout. If most of your work is small punch-list stuff, a shorter level is easier to stash. But if you regularly check openings, walls, frames, or long runs, the Empire EM75.78 78 in. Magnetic Box Level gives you the reach, hold, and visibility that make the job go smoother.
