A siding installation gauge includes a tool body, an upper support member, a clamp, and an actuating mechanism. A clamping portion of the clamp is inserted behind an installed lower siding board and the tool actuated to secure the lower board between the clamp and tool body. An upper siding board rests on registration surfaces on the upper support member while it is fastened for installation. The clamp includes coupling and clamping portions; movement of the actuating mechanism to an actuated arrangement retracts the coupling portion into or through the tool body and thereby forces movement of the clamp toward the tool body to secure the lower siding board. In the actuated arrangement, the actuating mechanism retains the clamp in a clamped arrangement; in the non-actuated arrangement, the actuating mechanism permits movement of the clamp into a non-clamped arrangement.

A siding tool for siding installation in building construction to efficiently measure the distance between adjacent siding panels and to install siding. The body of the siding tool is preferably approximately 3/16 ( 3/16 inches) wide, and a depth of approximately two inches (2). The width and depth are used to measure distances according to building code. The body has a lip at one end that extends from the base of the body. The lip is configured to position the siding tool in place by catching the bottom edge of a panel of siding that has been placed. The lip of the siding tool is also configured for a user to position the siding tool upside down and use the lip to draw measurement lines.

A tool for adjusting driven truss components and assembled truss foundations. A bridge separates a pair of collars, each having a pair of offset bearing surfaces that fit around the truss legs. A lever arm terminating in a handle extends away from the bridge to give leverage to the tool operator. The bridge width is adjustable to enable positioning of the tool at different heights along the driven truss components. An additional receiver proximate to one of the collars may enable single leg operation. Lateral and angular adjustment of the lever arm with respect to the bridge may enable greater force to be applied to one leg relative to the other.
