A cement siding tolerance device and measurement tool, which has a main panel having a tab and a ridge, whereby the tab and the ridge perpendicularly extend from the main panel at opposite sides. The main panel has a front face, a rear face, a top edge, a bottom edge, first and second lateral edges, and a plurality of holes. The main panel has ruler-markings adjacent to the first and second lateral edges. The main panel is rectangular in shape. The tab perpendicularly extends from the front face separated a predetermined distance from the bottom edge, and the ridge perpendicularly extends from the bottom edge at the rear face. The tab and the ridge measure clearances and gaps between siding and trim products with solid surfaces building elements.

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 drywall cutting tool is described. The drywall cutting tool has an elongated flat ruler with a knife blade and a handle attached to one end of the elongated flat ruler. A support bracket that has a flat top portion with a flange along one side and a pair of guides on the top. The guides receive the one end of the ruler allowing the ruler to slide along the top portion of the support bracket to any desired measurement length. A screw-down hand is also attached to the support bracket to pinch and secure the ruler at the guides so that the desired measurement length is maintained.

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.

The adjustable laser line, level, and square is a leveling tool. The adjustable laser line, level, and square comprises a pedestal, a slewing bearing, a stanchion, a drafting triangle, and a laser. The laser and the drafting triangle are attached to the stanchion. The slewing bearing attaches the stanchion to the pedestal. The laser generates a straight beam of light that is used to form a straight line along the surface. The adjustable laser line, level, and square allows for the adjustment of both the azimuth angle and the polar angle of the laser. The slewing bearing is used to adjust the azimuth angle. The drafting triangle is used to adjust the polar angle. The stanchion further comprises a plurality of bubble levels that measure the angle of the stanchion relative to the force of gravity.
