Designing machinery may not be the most artistic pursuit in the world, but sometimes the issue of color can be essential even in industrial design. A number of our metal parts can be produced in a variety of colors using a powder coating process.
JW Winco has its own in-house machining facility; this provides an advantage for our customers to take an idea and create a unique customized solution through the choice of using one of our standard parts.
Due to their cylindrical design, bull´s eye levels GN 2281 are suitable for installation in plates and housings where they serve to check the horizontal position of jigs, machines and devices.
Bull´s eye levels are not aligned, i.e. there is no reference to the external outline of the level. The vertical position must be ensured by aligning the holding building element.
The black housing of the version ALS creates a reflection at the edge of the bubble which significantly improves the readability. Version KT is available with contrast ring inside the air level housing(Identification no. 2) which creates the same effect.
Alternatively, the contrast can also be improved by a dark surface inside the mounting bore hole.
