Abstract
A level includes a level body having top, bottom and side walls, and a window that opens into the interior of the body. A level vial, which is secured to a vial mount, is positioned within the window opening. A vial retainer is secured within the interior of the level body, and includes a lower portion engaged with the bottom wall and upper portions engaged with the upper wall on either side of the window opening. The vial mount is secured to the vial retainer to secure the vial in a position in which the vial is visible from the exterior of the level body through the window. A vial position adjustment arrangement is provided for adjusting the position of the vial relative to the level body when the vial mount is secured to the vial retainer.
