Spirit Levels with Adjustment and Cross-Measurement
The GN 2276 cross spirit levels and GN 2283 screw-on spirit levels from JW Winco are essential for achieving perfectly horizontal alignment of machines, mechanisms or instruments. A company conversion table helps customers identify which sensitivity is best for various applications.

In digital times, they seem like relics from the past, but spirit levels remain indispensable tools in everyday industrial operations. Two new spirit level types from JW Winco (New Berlin, WI) offer better and faster alignment: GN 2276 cross spirit levels and GN 2283 screw-on spirit levels.
These small tools for adjustment are essential when striving for perfectly horizontal alignment of machines, mechanisms or instruments. And even after the initial setup, spirit levels still come in handy during regular operation to show whether the positioning is still correct. Spirit levels can be used almost anywhere.
In addition to needing no power supply or data lines, they are robust, simple to adjust and can be added at any time.
Cross spirit levels GN 2276 combine two perpendicular linear levels within a single, round aluminum housing. This design shows the alignment in two planes at once, making installation and leveling easier and faster. Winco offers two versions: One with a flat underside for direct installation and a second version with an alignment ball on the bottom side for adjustment. The second type, designated “JV,” allows the spirit level to be adjusted using the three installation screws to set a zero point adapted to the specific situation with a variance of +/- 2 degrees.
Winco’s screw-on spirit levels come in a robust aluminum housing. While the existing screw-on spirit levels GN 2282 have been in a deep-drawn, nonadjustable sheet metal housing, the new GN 2283 has the same properties as the right-angle spirit level GN 2276. The new screw-on spirit level is available both as a directly mountable, flat version “AV” and as an adjustable version “JV” with an alignment cam on the bottom. Here as well, the spirit level is adjusted during installation using the two socket cap screws.
Both the new linear and cross spirit levels are available in two sensitivity ratings: 2 millimeters of bubble movement correspond to either 6 or 50 minutes of arc. Winco offers a detailed conversion table to illustrate which sensitivity is best for various applications, making it quick and easy to compare height differences, degrees and minutes of arc.
