A hardboard installation support apparatus for mounting hardboard for board and batten siding installations includes a support bracket having a bracket front side, a bracket back side, a bracket top edge, a bracket bottom edge, a bracket left edge, and a bracket right edge. The supper bracket has a pair of mounting apertures extending from the bracket front side through the bracket back side. The pair of mounting apertures receives hardware to engage a building. A measurement indicator is coupled to the bracket front side and indicates a vertical distance from the bracket bottom edge. A support lip is coupled to the support bracket. The support lip is coupled to the bracket bottom edge and extends away from the bracket front side. The support lip and the bracket front side form an angle between 90° and 100°.

A square device and method of operation is disclosed. An example square device includes a first leg having a substantially same size height as width, and a second leg having a substantially same size height as width, the first leg and the second leg joined to form a substantially L-shape. The example square device also includes a substantially V-shaped groove formed all along an outward facing side of the first leg and the second leg, and a substantially flat clamping surface formed all along an inward facing side of the first leg and the second leg. When a first working article is received in the V-shaped groove formed along the first leg, and a second working article is received in the V-shaped groove formed along the second leg, the first working article is held in a substantially perpendicular orientation relative to the second working article.

A device includes a ruler, a leveling device attached to the ruler and a plurality of pins. The device only requires one person to hang level pictures, paintings, frames and other wall hanging objects. The ruler is a made from a rigid material and has a plurality of holes therein where the pins are inserted. The ruler has a fixed length or has a telescopic structure. The plurality of holes formed in the ruler are spaced apart from one another and the spacing is uniform or variable spacing. The leveling device is a bubble leveler including three bubble levels where one bubble level is horizontally positioned, another bubble level is vertically positioned, and the third bubble level has an angle relative to the horizontally positioned bubble level. The plurality of pins include a threaded pointed screw with a knob attached to one end of the screw.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

An adjustable strip cutting ruler may be provided. The adjustable strip cutting ruler may include a ruler body with at least one track for slidably mounting a glide. The ruler body may include measurement markings to align the glide at a desired width for cutting strips. The adjustable strip cutting ruler may further include fasteners for mounting the glide to the tracks of the ruler body.

An apparatus for determining the safety of a working environment comprising a panel assembly including first D-Ring indicia corresponding to D-Ring height, a first slider supported for movement relative to the panel assembly, the first slider including first anchor height indicia corresponding to anchor height and a Free Fall Distance (FFD) indexing arrow, a second slider supported for movement relative to the panel assembly, the second slider including FFD indicia corresponding to FFD first lanyard length indicia corresponding to lanyard length. The first slider is moved to a first slider FFD calculation position based on a determined anchor height. The second slider is moved to a second slider FFD calculation position based on a determined lanyard length and a determined D-Ring height. The FFD is determined based on a relative position of the FFD indexing arrow on the first slider and the FFD indicia on the second slider.

An inspection and measurement device includes a body defining a first planar face within a first bounded area, a first reference feature disposed on the first planar face within the first bounded area and corresponding with a first measurable parameter for structural inspection, and a second reference feature disposed on the first planar face within the first bounded area and corresponding with a second measurable parameter for structural inspection. The first and second reference features are positioned within the first bounded area for placement adjacent an element bearing the respective one of the first and second measurable parameters, and the first and second reference features overlap within the first bounded area in at least one direction.
