The Klein Tools 93PLL Rechargeable Self-Leveling Green Planar Laser Level is a three-plane layout laser for electricians, drywall and framing crews, tile setters, and remodelers. This is a self-leveling laser level designed for aligning studs, conduit, tile, concrete forms, and fixtures across a full room. Model Number 93PLL.

Most cross-line lasers throw a short fan of light in front of the tool. The 93PLL projects three full 360-degree planes: one horizontal (X) and two vertical (Y and Z) set at right angles to each other. Run them one at a time or all together. With all three on, you get a level line around every wall and two square plumb lines crossing the ceiling and floor, which is what you need to lay out a room square instead of chasing it one wall at a time. Where the two vertical planes cross, they give you plumb reference points up and down, which finds plumb much faster than hanging a string bob.

Green beams are the reason to pick this laser over a red one. The human eye picks up green light far more easily, so the lines stay readable at distance and in bright interiors. Klein rates the 93PLL at plus or minus 3/16" per 49 ft (4.5 mm per 15 m) of accuracy with an indoor working range of 200 ft (60 m). It is a Class 2 laser, with output of 1 mW or less per beam at 510 to 530 nm.

The self-leveling pendulum sets the lines automatically once the laser is on a reasonably level surface, and a transit lock secures the pendulum when you move it between rooms. Klein's integrated magnetic mounting bracket uses rare-earth magnets to grab steel studs, track, and panel enclosures, and it has 1/4-20 threads to mount on a tripod such as the Klein Tools 69345 adjustable tripod. That makes it easy to put the laser exactly at the height you are working, whether that is outlet height, a ceiling grid, or a chair rail.

Power comes from an integrated rechargeable lithium-ion battery that runs more than 9 hours on a charge, which covers a full shift of layout. It charges through a USB-C port with the included USB-A to USB-C cable, and a low-battery indicator tells you when to top it off. The housing is ABS with an IP54 rating against dust and water spray.

At 1.4 lbs (0.6 kg) and about 5-1/2" x 4-13/16" x 3-1/2" (140 x 122 x 89 mm), the 93PLL is light enough to hang from a magnet on light-gauge track without sagging, and small enough to live in a bag with the rest of your layout tools. Everything packs into the included hard carrying case.

Who should buy it? Electricians setting boxes and running conduit, interior contractors hanging drywall, ceiling grid, and cabinets, tile setters laying out floors and walls, and serious remodelers who want one laser that handles level, plumb, and square. If your work moves outside or needs grade work over long distances, a rotary laser such as the Klein 93RLS green rotary laser level is the better tool.

The Klein Tools 93PLL Rechargeable Self-Leveling Green Planar Laser Level Does a Whole Room at Once

Three green 360-degree planes and a rechargeable battery put this laser in the do-everything category for interior layout.

• Who it's for: Electricians, interior contractors, tile setters, and remodelers who lay out level, plumb, and square every day.
• Why it stands out: Full 360-degree coverage on all three planes, 200 ft (60 m) range, and a magnetic bracket built for steel framing.
• Worth knowing: The tripod is not included, and this is an interior layout laser. For long outdoor or grade work, step up to a rotary laser.

• How accurate is the 93PLL? Klein rates it at plus or minus 3/16" per 49 ft (4.5 mm per 15 m).
• How long does the battery last? More than 9 hours per charge from the integrated lithium-ion battery.
• Can I run just one line? Yes. The X, Y, and Z planes project independently or together.
• Does it come with a tripod? No. It includes a magnetic mounting bracket with 1/4-20 threads that fits standard tripods.
