A level includes a body comprising a first portion having a first reference surface, and a second portion having a second reference surface, the second reference surface being spaced from the first reference surface. The body also includes an intermediate member comprising a wall positioned between the first and second portions, the wall being generally perpendicular to at least one of the reference surfaces. The level also includes an orientation indicator coupled to the intermediate member, the orientation indicator being positioned to indicate an orientation of at least one of the first and the second reference surfaces. The level additionally includes an indicator support configured to support the orientation indicator, and a resilient member positioned between the orientation indicator and the indicator support. A compression the resilient member facilitates a calibration of the orientation indicator, while the indicator support supports the resilient member and engages opposite sides of the wall. |
