A hanger for hanging an object on a vertical surface includes a plate with a front face and a back face. The back face is to abut a vertical surface onto which the object is to be hung. The hanger includes a first hook and a second hook protruding outward from the front face and an integrated bubble level fixably coupled to the front face and calibrated to indicate a horizontal orientation of the first hook relative to the second hook. A plurality of wall contacts protrudes outward from the front face. Each wall contact includes an opening through which an attachment mechanism traverses to attach the plate to the vertical surface. The hanger does not require the object to have a specifically shaped counterpart in order to interface with the hanger. The hanger removes the need for elaborate and/or time-consuming measuring, thus saving the user time and frustration.

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 hands free level has a body having a first end, a second hook shaped end, and a level device. The level device has a tube partially filled with a liquid that has a bubble, a first left end marking, a first right end marking, a second left end marking, and a second right end marking, the first left end marking and the first right end marking defining a center portion in which the bubble is positioned to indicate level, the first left end marking and the second end marking defining an incline portion in which the bubble is positioned to indicate an incline grade, and the first right end marking and the second right end marking defining a decline portion in which the bubble is positioned to indicate a decline grade.

An extendible or adjustable length level is provided. The level includes a locking mechanism allowing the user to fix the level at a selected or desired level. The locking system allows the user to lock the level at the desired length and provides more effective and robust locking than conventional expanding levels. In some embodiments, the locking mechanism is designed such that translational movement of the user-actuated control (as opposed to rotational motion) is used to move the locking mechanism into the locked position.

A sensor mounting device and method to accurately mount a sensor to a test asset for data collection and component validation, the sensor mounting device including a leveling plate equipped with a level indicator, an alignment shelf adapted to constrain the movement of a sensor and hold the sensor level relative to the level indicator, and various protruding structures for aligning the mounting device with the test asset. The sensor mounting device may further include a base structure to support the leveling plate and allow a user to adjust the vertical position of the sensor to be mounted. The base structure may include a plurality of spanning members on which the leveling plate is mounted as to allow the leveling plate to be adjusted vertically.

An extendible or adjustable length level is provided. The level includes a frame, a slidable member, and a bushing. The slidable member is coupled to the frame and extends and retracts along the frame. The bushing is coupled to one of the frame or the slidable member and couples the frame and slidable member together.
