Heavy Duty Levels

These sturdy levels last longer than typical levels, even if you use them frequently. With four solid sides that form a box shape, they stay flat on surfaces without wobbling and won’t twist or deform over time. The aluminum housing and durable plastic vial won't crack if you step on them or drop them off a ladder or tool tray.

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

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.

Levels with Ruler—Align and measure surfaces without having to switch tools.

Levels with Center-Finding Ruler—Quickly locate the center of your workpiece without any math. These levels have graduation marks that start at zero in the middle of the level. Just align them so that the increments are the same on both sides of the object you’re measuring —zero marks your center.

Levels

Your go-to option for day-to-day leveling. Made from aluminum, these levels won't crack or warp the way plastic ones do. Lay them against everything from building frames to floor tiles to make sure your surface is level horizontally, vertically, or at an angle.

Angle-Measuring Levels—Measure precise angles while leveling without switching tools. To find the angle of your surface, rotate the angle indicator vial until the bubble is level.

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

Digital Levels

Pick these digital levels for repeat leveling tasks and tired eyes. With a digital display for clear reading and an audio alert that sounds when your surface is perfectly level horizontally or vertically, you can quickly align a workpiece before moving on to the next surface. The false zero setting lets you set any position as a reference point when you need to replicate angles on multiple surfaces. You can also view the angle, pitch, or slope of a surface without a separate tool. Use the horizontal and vertical bubble vials on these levels to recalibrate the sensor if needed and as a backup option if your level runs out of battery.

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

Levels for Tight Spaces

Levels

Squeeze these levels into places a standard level would never fit. Their short length and tapered ends make them ideal when you're leveling small parts or working in tight corners. Also known as torpedo levels, they're commonly used by plumbers leveling drains under sinks or by electricians installing components behind electrical panels. Rest them on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

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

Angle Measuring—Measure precise angles while leveling without switching tools. To find the angle of your surface, rotate the angle indicator vial until the bubble is level.

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.

Post Installation Levels

Achieve perfectly upright posts and poles with these levels. Their L shape allows them to nest securely around flat or curved surfaces. They have two hooks and come with a heavy duty rubber strap to secure them around pipes of any size. The vertical vial tells you when your post is plumb. The two horizontal vials level your pole horizontally so it isn’t tilting forwards, backwards, or sideways.

Extendable Long-Distance Levels

Level horizontal and vertical surfaces up to 10 or 12 feet. Pull out the extendable portion of these levels to reach across the entire length of doors, windows, and large frames for accurate readings. Push it back in and use the two hand grips for easy carrying. The extendable section has a ruler on both sides to measure distances without extra tools.

Low-Light Levels for Tight Spaces

Level surfaces inside machinery, behind equipment, or anywhere too cramped for light to reach. The vials on these levels illuminate for clear reading without a flashlight. Also known as torpedo levels, their compact size and tapered ends make them ideal when you're leveling short surfaces or working in tight corners. Rest these levels on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Levels with Glow-In-The-Dark Vials—Expose these vials to ambient light to charge them and they'll stay visible in dark areas, no batteries needed.

Pitch-Measuring Levels with LED Vials—Use the incremental marks on the horizontal vial to find the incline of surfaces while you level. LED lights illuminate one vial at a time, so you can read it clearly without the other lights creating glare.

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

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.

Nonstick Levels

Level bricks, tile, concrete, and other sticky or wet materials. Traditionally used by masons, these bamboo levels have a lacquer coating that makes grout and mortar slide right off them.

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.

Heavy Duty Low-Light Levels

Don’t fiddle with a flashlight – these levels light up in dimly lit or completely dark work areas. With a box-style body, these levels won’t twist or deform and stay flat on surfaces without wobbling. The aluminum housing and durable plastic vial keeps them from cracking if you drop them off a ladder or tool tray.

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.
