Levels and squares for carpentry, plumbing, electrical, conduit bending, equipment installs and layout.

What to check before you order

  • Length. Short torpedo levels fit in panels and between studs. Longer levels average out uneven surfaces on walls, doors and frames.
  • Vials. Look for plumb, level and 45 degree vials as needed. Some levels add a vial for conduit bending angles.
  • Magnetic edge. Magnets hold the level on steel pipe, conduit, strut and machine bases.
  • Check accuracy. Flip the level end for end on a flat surface. A good level reads the same both ways.
  • Squares. Framing squares for big layout, speed squares for quick cut lines, and combination squares for machine and bench work.
  • Laser safety. Follow the manufacturer's laser class warnings and never aim a laser at anyone's eyes.

Common questions

What is the difference between a speed square and a framing square?

A speed square is a small triangular square with degree and rafter markings, used to mark angled cuts and as a saw guide. A framing square is a large L-shaped square, commonly 16 x 24 in., used to lay out stairs and rafters and to check larger corners.

How do I check a corner for square without a square?

Use the 3-4-5 method. Measure 3 ft along one side and 4 ft along the other, then measure the diagonal between those marks. If the diagonal is exactly 5 ft, the corner is 90 degrees, and you can scale the numbers up, such as 6-8-10, for bigger layouts.
