Siding panels for covering the exterior wall of buildings mutually define a tongue and groove interfit which facilitates installation by placing the weight of an upper panel on an underlying lower panel instead of requiring an installer to hold the panel in place against gravity. Mounting nails are used in combination with the tongue and groove interfit to positively lock the tongue of one panel into the groove of the underlying panel. Nail placement is controlled by the relative placement of nail slots and hammer abutment surfaces formed on each panel. Because the panels must be pivoted in place and held in place by the overhanging siding nails, it is virtually impossible for the installer to make a mistake that results in an upper siding panel coming loose from the siding panel below.

DETAILED DESCRIPTION The present invention has been developed to fulfill the needs noted above and therefore has as an object the provision of a siding panel which is easy to install and which forms a positive locking interengagement with an adjacent panel.
Another object of the invention is to provide a plastic siding panel which controls and sets the amount of nail projection above the surface of the panel during its installation.
Another object of the invention is to provide a vinyl siding panel which is self-positioning and self-seating by its own weight.
Another object of the invention is to provide a siding panel which does not need to be held by an installer and supported against falling or slipping downward during installation.
Still another object of the invention is the provision of a seamless vinyl siding panel or a cut to length panel which uses mounting nails for both mounting a first panel to a wall and for providing a positive step for preventing disengagement of a second panel from the first panel.
Another object of the invention is to prevent an installer from pulling siding panels upward to correct misalignment that the installer created, thereby preventing panels from becoming disengaged.
These and other objects are met by the present invention which is directed to a siding panel, particularly a seamless plastic siding panel or panels cut to length, which includes an abutment surface or surfaces for engaging a hammer during installation of the panel.
The abutment surfaces establish the final position of the heads of the mounting nails so as to establish a predetermined final location of the nail heads and a predetermined length of nail projecting from the wall being covered with the siding.
The location of the mounting slots or holes for receiving the mounting nails is aligned with respect to an adjacent locking channel or groove so as to position the mounting nails in an interference relationship with a mounting lip formed on another mating panel.
This particular construction requires a unique pivoting motion for locking the mounting lip of one panel in the locking channel of another previously installed nailed down panel
