摘要： An extendable level includes a base frame having an internal passage, an extension member positioned within the internal passage and movable between an extended position and a retracted position relative to the frame, and a retainer mechanism for securing the extension member in position relative to the frame. The retainer mechanism is in the form of a modular retainer assembly that can be assembled as a unit to the base frame. The retainer mechanism includes a positioning arrangement that is configured to prevent movement of the extension member relative to the frame at predetermined positions of the extension member relative to the frame via a first engagement arrangement, and is further configured to resist movement of the extension member relative to the base frame at locations between the predetermined positions via a second engagement arrangement.

摘要： A tool, such as a level, including one or more polymer/plastic body segment, protective cover and/or seal is provided. The covers discussed herein may limit or prevent dirt or construction materials, such as concrete, from entering into the level body. The cover may also be a non-stick material, such as a polymer outer sleeve, that limits the ability of dirt and construction material to adhere to the level. The level may also include scratch resistant vial windows.

摘要： This unique and novel invention provides a telescoping level device used to effectively and efficiently measure the slope of objects and surfaces. The device comprises a telescoping arm, a ball joint, a level, and one or more contactors. The device allows the user to easily, accurately, and quickly verify the in-situ slope of pipes as well as a plurality of other objects and surfaces. The length and angle of the telescoping arm, relative to the level, are adjustable to prevent the user from unnecessarily stooping, kneeling, or climbing.

摘要： Devices, systems and methods for hanging one or more objects, such as frames, on a surface. A marking device for marking a surface for hanging one or more objects. The marking device can have a main body portion having first and second arms pivotably attached thereto. The first and second arms, as well as the main body, can each have a marker to mark a target surface. The marking device can optionally have a level indicator and the first and second arms can have markers which can slide along a ruled measure for convenient positioning of marks on the target surface. Optionally, the markers can have biased, retractable, or sheathed marker pins.

摘要： A method for measuring an operating temperature of equipment which can be oriented in a defined state using a leveling instrument, where the leveling instrument includes at least one tilt sensor with a housing that is filled with a liquid and a gas bubble, a light source, and a photosensor. The method includes storing a characteristic curve of bubble lengths for the gas bubble and temperatures in a control device of the equipment, measuring the bubble length of the gas bubble, and determining the temperature associated with the measured bubble length of the gas bubble with the aid of the characteristic curve.

摘要： A trip hazard measurement gauge is, except for a measurement module and display, constructed primarily of aluminum. A cylindrical tube has an upper straight section and a lower straight section that are interconnected by a curved section. The upper straight section and the lower straight section form an obtuse angle. A cylindrical aluminum housing is connected to the tube via a conical connecter piece. A non-movable foot is rigidly connected to the cylindrical housing. A measurement module is installed within the cylindrical housing. A slidable rule, to which a movable foot is attached to a lower end thereof, extends from the measurement module. A return spring ensures that the movable foot returns to its lowermost position. After turning ON the display, selecting the measurement system and zeroing the gauge, it is ready to measure differences in elevation between adjacent sidewalk slabs.

摘要： The present disclosure provides a globe clamp with integrated mounting pads which can hold a level while a user adjusts the lighting device to which the globe clamp is coupled. In one example embodiment, the globe clamp includes a clamp body, which includes a top portion, a bottom portion, and an exterior contour. The top portion forms a first internal opening defined by a first inner surface. The bottom portion forms a second internal opening defined by a second inner surface. The exterior contour surrounds the top portion and the bottom portion. The exterior contour comprises at least one recess having a horizontal, flat surface, the recess configured to retain a level.
