An assembly for mounting to a head-worn accessory, the assembly includes a body configured to be affixed onto the accessory. The body has a level bubble tube. A second body configured to be affixed onto the accessory, the second body having a second level bubble tube. The second body is pivotably attached to the first body by a connection that allows pivoting of the second body relative to the first body.

A conduit level for determination of conduit bend angles includes a frame supporting a plurality of bubble levels at various angular orientations. The frame has first and second opposite sides, a bottom edge extending along an axis, a top edge, and a front end edge connecting the bottom edge and the top edge. Each of the bubble level sensors has a unique angular orientation relative to the axis of the bottom edge of the frame. The frame includes at least one bubble viewing slot allowing a user to view the plurality of bubble levels in edgewise viewing directions facing the top edge and the front edge of the frame, and a plurality of bubble viewing windows allowing the user to view the plurality of bubble levels in a sidewise viewing direction facing at least one of the sides of the frame.

A level including level vial(s) having enhanced visibility are provided. The level may include a level vial including a material that is attracted to the interface or border of a globule within the level vial which improves visibility of the interface. The level may include a solid level indicator having easy to see end surfaces that are generally vertically oriented when in the level position. The end surfaces of the solid level indicator may allow the user to more easily compare the position of the solid level indicator to indicating lines formed on the level vial. The level may include a level vial including a first liquid and an immiscible second liquid forming a globule with the first material. The globule formed from the second material may improve visibility compared to a typical air bubble.

The level correcting gauge block is a tool. The level correcting gauge block incorporates a stepped structure, a level tool, and a target surface. The level tool is a tool used to identify a plane that is perpendicular to the force of gravity (called a horizontal plane). The level tool is used to determine whether the target surface is parallel (or “level”) to a plane that is perpendicular to the force of gravity. The stepped structure works in conjunction with the level tool. The stepped structure measures the elevation change required to be made to the target surface to bring the target surface to level.
