Johnson Aluminum Box Level 72 in 1717-7200

Johnson 72-Inch Aluminum Box Level

This Johnson aluminum box level measures 72 inches long and 3.300 inches wide with a yellow finish. It is designed for carpenters, electricians, plumbers and machinists who need to verify level and plumb on construction sites. The top-read feature allows easy viewing of the vial from above. Model 1717-7200 is nonmagnetic and built for professional trade use.

Suited For Long-Span Alignment

This level suits tradespeople checking extended runs such as wall plates, door frames and drainage pipe where a shorter tool cannot reach. It is not intended for users who need magnetic attachment to steel studs or beams. Workers requiring a compact tool for tight cabinets or conduit bends should look at a shorter length. The nonmagnetic body also limits use on vertical metal surfaces where hands-free holding is required.

72-Inch Length Decides Fit

The single specification that determines whether this is the right part is the 72-inch length. That span covers standard door heights and typical stud bay spacing in a single placement. If the work involves shorter spans or confined spaces where a 72-inch body cannot manoeuvre, a different length is required. No other dimension overrides this basic reach requirement.
