A base extension assembly for measuring angles on a radiused corner includes a base that has a blade slot extending therein to insertably receive a blade of a combination square. The base has a channel is integrated therein to receive an anvil of the combination square. The base has a width that is greater than the width of the anvil such that the base extends beyond a radius of a corner is measured with the combination square thereby enhancing accuracy of the combination square. A pair of plates is each of the plates is positionable on the base to retain the anvil of the combination square in the channel.

A roof square for marking rafters comprising a right angle triangular body with a marking blade pivotally mounted adjacent the right angle. Either side of the square adjacent the right angle is held against the stock to be marked, and the blade used to mark either a plumb cut or a foot cut. The blade retracts to allow marks to be made at a measured depth. The tool can also be used as a conventional square to make 90 and 45 degree marks.

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 T square alignment device for providing enhanced flexibility while cutting drywall or other planar objects. The adjustable T square alignment device comprises a blade defining a rigid, elongated structural body having an integral elongated sliding slot, a head defining a rigid structural member having a wide base portion and a narrow sliding portion, and a fastening system operative to both secure the head to the blade, with the sliding portion positioned in the sliding slot, and fix the head at a desired lengthwise position on the blade. In this regard, the head may be selectively repositioned along the length of the blade by sliding it lengthwise but not moved angularly relative to the blade.

Assemblies and methods for applying painter's tape to a wall for painting stripes thereon wherein the assembly has a first elongated body with a first straight outer edge, a second elongated body having a second straight outer edge with a substantially transparent body and having a tape width guide marking substantially along the elongated body with a plurality of elongated markings parallel to the second straight outer edge, two or more arms each having ends rotatably coupled to the first and second elongated bodies respectively, each of the arms being spaced apart of another and coupled at different positions of the elongated bodies, and a coupling mechanism rotatably coupling an arm to one of the elongated bodies and having a locking feature selectively fixing the angular position of the coupling mechanism and preventing rotation of the rotatably coupled arm relative to the coupled elongated body.

Disclosed is a tool including: first and second members that respectively define: first and second forward ends; first and second bodies that extend along respective first and second elongate axises to first and second aft ends, wherein the first and second forward ends are pivotally connected to a pivot member, whereby the first and second members are configured to pivot about a pivot axis, so that the first and second aft ends move toward and away from each other; and a third member that defines a first transverse end and a third body that extends along a third elongate axis to a second transverse end, wherein: a first slide lock is fixed to the first transverse end of the third member and is operationally connected to the first member; and a second slide lock is operationally connected to the second member and the third member.
