A conduit marking tool is fashioned as a rectangular prism having a bore passing through the center thereof. A plurality of perpendicular notches is disposed on one (1) of oppositely positioned frame faces. A set screw is disposed on a side of the tool between the faces. The tool permits a user to score or otherwise mark apportion of conduit for subsequent tasks.

A wall hanging device for marking the location of wall mounting fasteners is provided. The wall hanging device intrinsically locates connection points along a wall that correspond with connection points along an article to be hung on the wall. The systemic device provides two opposing surfaces, each surface providing corresponding guide markings. Each surface also has adhesive elements so that the device can first be adhered to the article and then transferred to the wall by way of urging the article against the wall, thereby ensuring that one or more preselected connection points along the article, first associated with one surface's guide marking(s), are intrinsically located on the wall by way of the other surface's corresponding guide markings after pulling away the article, leaving the temporarily adhered device to the wall. The device also provides a foldable pocket for capturing debris resulting from the installation of the mounting fasteners.

The hammer has a head and a handle which extends from the head. The head has at least two surfaces that face towards the handle and that lie in a common first plane. At least a portion of the handle extends linearly and perpendicularly from the first plane to allow a user to draw a straight line which is perpendicular to the first plane.

A method of verifying placement of a piece on a work surface is disclosed. An imaging device and an illumination system are electronically interconnected with a computer. The illumination system projects indicia onto a work surface for indicating a location for placement of a piece on the work surface. An indicator is provided to the piece that includes light emission displaying fluorescent wavelengths when illuminated for distinguishing the piece form the work surface. The piece is placed upon the work surface at a location indicated by the laser indicia. The illumination system illuminates the piece presenting a visible contrast between the piece and the work surface enabling the imaging device to distinguish the piece from the work surface. The imaging device signals the controller a location of the piece for the controller to verify accurate placement of the piece.

An angle measurement apparatus for use with a panel such as siding is provided. The apparatus includes a base portion defining a locating feature that is engageable with a reference feature on the panel. An arm portion is rotatably mounted with respect to the base portion such that the arm portion is selectively rotatable with respect to the base portion about an axis. The arm portion can thus be rotated to form a desired angle with the base portion, and, correspondingly, with the panel.

A tool and system for measuring the size, position, and spacing of rebar in a concrete structure comprises a card preferably having a linear periphery. Around the periphery are a plurality of cutouts, with each of the cutouts adapted to measure the diameter of a standard rebar. The periphery of the card also has a series of hash marks to determine linear measurements. The amount of clear cover of the resulting concrete is measured by placing the tool on rebar inboard of the formwork and counting the hash marks to the adjacent formwork. The spacing between two rebars is measured by placing the tool on one rebar and counting the hash marks between two rebars. Alternatively, the distance between rebars and rebar overlap length is estimated by using the tool to determine the scale, if the space between bars is and overlap is longer that the tool length.
