Abstract: The subject invention provides a portable saw table assembly for cutting a material longitudinally, laterally, and at various angles thereto. The assembly includes a first and a second table rail being parallel and spaced from each other and each extending between a proximal end and a distal end. A saw rail is moveably supported by the first and the second table rails for moving longitudinally along the table rails between the proximal and the distal ends and a mounting plate is moveably supported by the saw rails to allow movement of the mounting plate laterally along the saw rail between the first table rail and the second table rail. A saw plate is rotatably supported by the mounting plate for carrying a saw to cut the material. A guide bar is disposed diagonally relative to the first and the second table rails and engages the saw plate to guide the saw plate diagonally in response to simultaneous movement of the saw rail longitudinally and the mounting plate laterally.

Abstract: A water deflection system is provided for use with a wall mounting assembly, wherein the water deflecting system and the wall mounting assembly are suitable for mounting to a wall of a structure, such as a building. The wall mounting assembly includes a mounting plate and a cover plate. The mounting plate and the cover plate of the wall mounting assembly are spaced apart from one another and/or provide sufficient clearance to allow for a downward flow of water therebetween. The water deflection system interrupts, channels, and/or directs this downward flow of water and safely diverts the water away from the region proximate to the top portion of the cut hole towards a region proximate to and/or below the bottom of the cut hole, thereby preventing the damage associated with water being introduced behind the siding.

Abstract: A wall mount assembly for mounting to a building is described. The wall mount assembly includes a base member having a front surface and a rear surface and having a wall extending about an outer periphery and inwardly from the rear surface. The base member also includes at least one edge recessed rearwardly from the front surface defining a recessed portion therein.

An annular flange extends rearwardly from the recessed portion. An insert member and/or a cover member mount to either one of the mounting apertures, mounting holes and/or mounting surfaces for creating an aesthetic appearance.
