Two-Axis Surface-Mount Levels


A	B	C

Mount these levels to workbenches, platforms, and tabletops to keep them horizontally level in two directions. Use them to make sure surfaces stay aligned over time.

Screw-On Levels—Fasten these levels to any drillable surface for the most secure mount that won't shake loose, even on vibrating equipment. Fasteners are not included.

Pitch Measuring—Level and determine pitch with one tool. The horizontal vial has incremental marks that indicate the incline of surfaces such as drainage pipes, conveyor chutes, and roofs.

Plastic Housing—While not as durable as aluminum levels, these are a lightweight and economical option.

Two-Axis Precision Levels


Straight	Square

Triangle

Level horizontal surfaces in two directions at the same time with the highest degree of accuracy. The highly sensitive glass vials on these levels sit perpendicular to one another – place them on the corner of platforms and surface plates to check if they’re tilting sideways, forwards, or backwards.

Levels with Calibration Certificate—When precision readings are required for quality control or by regulation, use a level that includes a calibration certificate traceable to NIST. The certificate states that the level has passed a test for accuracy, so you can be confident your readings are correct and consistent.

Cast Iron Base—Heavy cast iron keeps your level stable on surfaces and won't contract or expand in extreme temperatures.

Starrett—These levels are machined in the U.S. by Starrett, one of the most trusted names in precision measuring tools.

Multi-Axis Levels

Simultaneously check if a surface is level horizontally and vertically, as well as front-to-back. Use one of the three main vials on these levels to determine if your surface is completely flat, upright, or at a 45° angle. Plug in the fourth vial to level two axes at the same time. Use them to level cross-sections of pipe, frames, and other three-dimensional parts.

Rest them on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Pitch-Measuring Levels—Level and determine pitch with one tool. The horizontal vial has incremental marks that indicate the incline of surfaces such as drainage pipes, conveyor chutes, and roofs.

Magnetic Levels—Stick to metal surfaces for hands-free leveling.

Two-Axis Surface-Mount Precision Levels

Mount these levels onto CNC machines and other equipment for repeat horizontal level checks in two directions at the same time. With a highly sensitive glass vial and a heavy cast iron base for stability against surfaces, they detect even the smallest tilts backwards, forwards, or sideways, so you can correct them before they affect machine performance.

Screw-On Levels—Fasten these levels to any drillable surface for the most secure mount that won't shake loose, even on vibrating equipment. Fasteners are not included.

Combination Six Crosshair Line Automatic Leveling Laser Levels

No need to reposition these lasers as you work around your room—crosshairs on every surface give you all the reference points you need. They are a good choice for level, plumb, and square applications, such as aligning doors and windows on multiple walls. If you set them on a surface, they level themselves within about 4° and indicate when they are out of level. You can turn this function off when you want to make sure your crosshair is level with something other than the Earth.

Secure them to a tripod using the threaded mount or use the strong magnetic base to attach them to equipment. They come with a magnetic target, which you can mount in your space to reflect the laser beam to increase its visibility in dim conditions and at far distances.

Multiple Dot Laser Levels

Project accurate level references onto walls and ceilings to hang light fixtures or install pipe. These lasers have four vials to verify the level, plumb, and square reference points are accurate. Because they’re red, the lasers are best viewed indoors. They have a screw-on mount to secure to a tripod, or you can use the magnetic base to stick them to equipment for quick checks. A V-groove on the body creates stability on curved surfaces, such as pipe or conduit. They’re powered by disposable batteries, so they’re portable and easy to use when you’re not near an outlet.

Combination Crosshair Line and Multiple Dot Automatic Leveling Laser Levels


2 Dots	5 Dots (Front View)

5 Dots (Back View)

Level equipment with confidence—in addition to a crosshair, these lasers also project plumb dots, so you know the laser is in the right spot. They’re an upgrade from a standard crosshair laser while remaining simpler than lasers with multiple crosshairs. Use these lasers to precisely install square elements, such as doors and windows. The crosshair extends along your wall, so you don’t have to reposition the laser often as you work around your room. If you set them on a surface, these lasers level themselves within about 4° and indicate when they are out of level. You can turn this function off when you want to make sure your crosshair is level with something other than the Earth.

2 Dots—Levels with two laser dots help you verify your installation is plumb with reference points above and below the tool. These red lasers are best for indoor environments, since they’re dimmer than green lasers.

5 Dots—Levels with five laser dots help you verify that your tool is positioned correctly in multiple dimensions with reference points above, below, behind, and to the sides of the tool without repositioning your laser. These green lasers appear up to 10 times brighter than red lasers, so they’re easier to see outdoors or in bright indoor lighting, as well as from far away.

Automatic Leveling Dot Laser Levels


3 Dots	5 Dots

Set these lasers on any surface, and they'll level themselves within about 4°. Whether you’re hanging a drop ceiling or aligning bench tops, they project accurate level references to make sure your installation will be at the right height. You can also mount them in a few different ways. They have a threaded insert to attach to a tripod (sold separately). Or use the magnetic base, which is strong enough to hold even on vibrating equipment.

Red Laser—Red lasers are best for indoor environments, since they’re dimmer than green lasers.

Green Laser—Green lasers appear up to 10 times brighter than red lasers, making them easier to see outdoors or in bright indoor lighting, as well as from far away.

5 Dots—Lasers with 5 dots help you verify your installation is straight, level, and plumb at the same time. This prevents you from having to reposition the level frequently, so you can work faster.

Strap Mount—Lasers with a strap mount can be secured on poles and ladders.
