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.

A framing tool includes a pair of slotted beams that are affixed together at each end using an end spacer of a thickness selected to maintain the two slotted beams at a separation that allows a framing square to slide easily but snugly therebetween. Then, a user can cause the slotted beams to clamp down on the framing square using two sliding clamps so as to trap the framing square between the two slotted beams. The first sliding clamp is slidable along a slot of the pair of slotted beams, and the second sliding clamp is slidable along a slot of the pair of slotted beams. The framing tool also includes: a pair of end-fixed spacer assemblies, a first end-fixed spacer assembly configured to squeeze together the first ends against an end spacer, and a second end-fixed spacer assembly configured to squeeze together the second ends against an end spacer.

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.

The present invention provides an installation device comprising a substantially planar first element having a first elongate body having a first end and a second end opposing the first end, the elongate body defining a first longitudinal axis and having a width w1 extending transverse to the first longitudinal axis, the elongate body defining a linear alignment indicator located at a midpoint of width w1 and extending along the length of the first element; and a substantially planar second element having a second elongate body having a first end and a second end opposing the first end, the elongate body defining a second longitudinal axis and having a width w2 extending transverse to the second longitudinal axis, the elongate body defining an engagement channel extending along a portion of the length of the second element, the second elongate body further comprising a plurality of position indicators along at least a portion of its length; and engagement means extending from the first element through the engagement channel and operable to secure the first and second elements to one another, wherein the installation device is moveable between a first configuration in which the first and second elements are pivotable relative to one another about the engagement means; a second configuration where the second element is slidable relative to the first element in a direction parallel to the second longitudinal axes; and a third configuration in which the first and second elements are fixed relative to one another. Also provided is a method of preparation of the aforementioned installation device and a method of use of the aforementioned installation device.

A combination square is provided with a square head that includes a pair of bores extending through a blade receiving slot, a pair of pins, each pin having an eccentric outermost surface and being engaged in a corresponding one of the bores, and a ruled blade that is releasably engaged in the slot such that the relative angle between the head and the blade can be adjusted by rotating one or both of the pins about the axis of the corresponding bore.
