48-Inch Aluminum Box Level

The Johnson 1717-4800 is a 48-inch aluminum box level designed for construction and trade professionals. Carpenters, electricians and plumbers use it to verify that surfaces and angles are level or plumb. Its yellow finish provides high visibility on busy job sites.

Non-Magnetic Top-Read Design

This level features a non-magnetic aluminum frame, so it will not cling to ferrous surfaces during layout work. A top-read vial window lets the user check level status from above without bending low. The 3.300-inch width gives a stable footprint on studs and beams.

Durable Construction for Daily Use

The aluminum body resists corrosion and stands up to repeated handling in normal trade environments. No moving parts or electronics mean silent operation and zero power draw. The rigid box profile maintains accuracy across the full 48.000-inch length.

Questions about this item

How does the 48-inch length help on a real job site?

The 48-inch span lets you check level and plumb across wide stud bays, door frames and long shelves in one placement, reducing the need to reposition the tool repeatedly.

What does the non-magnetic aluminum box construction mean for daily use?

The aluminum box frame resists warping and won't stick to steel studs or conduit, so you can slide it freely along metal framing without fighting magnetic attraction.

What clearance does the 3.3-inch width need to fit in a tool bag or on a scaffold board?

At 3.3 inches wide, the level fits standard scaffold planks and most open tool totes, but it will not slide into narrow pouches designed for torpedo-style levels.
