Abstract: A longitudinally-elongated, hand-held level includes a body having a reference surface, a longitudinally-extending corner adjacent the reference surface, and a plurality of bubble vials for indicating an orientation of the reference surface. One or more battery-powered lights (e.g., LEDs) create a longitudinally elongated light emitting region along the corner to illuminate a longitudinally-elongated area that is adjacent to the level for use in low-light environments. The light(s) may project light through a light guide and/or light diffuser(s) extending along the corner to disperse light along the longitudinal extent of the level. The light(s) may also illuminate the corner(s) of the level and/or the bubble vials to enhance use in low-light environments.

Abstract: A level includes a body having first and second arms attached to each other for relative pivotal movement about a pivot axis between open and closed positions. The level also includes a bubble vial mounted to the body and having a longitudinal axis coaxial with the pivot axis. Movement of the arms from their closed position to their open position exposes a measurement portion of the first bubble vial for use. Movement of the arms from their open position to their closed position shields the measurement portion of the first bubble vial within the body to protect the bubble vial from damage during storage.

Abstract: A device for determining the relationship of a surface relative to level is provided, the device having an elongated body portion and at least one attachment portion for attaching the elongated body portion to a workpiece. The at least one attachment portion may include a clamp or other attachment mechanism that can be stored in a storage position and deployed in at least one deployed position so as to attach the elongated body portion to the workpiece.
