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.

Questions about this item
What surface width can the 3.300 in wide level span without overhang?
The level body is 3.300 in wide so it sits flat on any surface at least that wide; narrower edges will leave the vial housing unsupported.
How does the non‑magnetic aluminum frame affect use near steel studs or conduit?
Because the box beam is non‑magnetic aluminum it will not cling to ferrous framing, so you must hold or clamp it in place when checking metal studs or conduit runs.
How do I confirm the top‑read vial is accurate after unpacking the 72 in level?
Place the level on a flat surface, note the bubble position, rotate it end‑for‑end and check that the bubble returns to the same reading; repeat on a vertical surface for plumb.
