Overview

Checking level and plumb on steel studs or conduit is easier with the magnetic Stanley FatMax, a single-piece aluminum box beam with block vials. A bridged center vial leaves an unbroken edge for marking lines.

Accuracy and toughness lead: block vials read to a tight tolerance, and the one-piece extrusion resists twisting on the job. The listing does not say how many vials it has or what warranty applies.

Who it's for

Trades who set boxes, conduit and steel framing benefit from a level that holds itself to metal. Deck builders and wall framers who need more length should choose a longer beam.

Pros and cons

Pros
  • Magnetic edge frees both hands
  • Block vials for tight accuracy
  • Full-length marking edge
  • Grip and end caps absorb drops
Cons
  • Number of vials not listed
  • Short length for long spans

Performance notes

Reading accuracy depends on the vials and the frame staying straight: block vials are set in a rigid box beam that resists bending and twisting. The magnets hold the level against ferrous surfaces so a reading does not shift while you mark.

Frequently asked questions

Will the Stanley FatMax magnetic level stick to aluminum?

The listing only calls it magnetic. Magnets hold to steel and iron, so it will not cling to aluminum or most stainless trim.

Can the Stanley FatMax level mark straight lines?

Yes. The bridged MaxEdge center vial leaves a continuous marking surface along the edge.

Is the Stanley FatMax a laser level?

No. It is a manual bubble level with block vials in an aluminum box beam.
