GN2281 Bull's Eye Level for installation in Plates & Housings.
Due to their cylindrical design, these bulls eye spirit levels are suitable for installation in plates and housings where they are used to check the horizontal position of jigs, machines and devices.
The black housing of the ALS version creates a reflection at the edge of the bubble which significantly improves the readability. The KT version is available with a contrast ring inside the air level housing (Identification number 2) which creates the same effect. Alternatively, the contrast can also be improved by using a dark surface inside the mounting bore hole.
These bulls 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.
