Architectural siding and method of use

A method for a siding product assembly, the method comprising:

• installing a first siding product on a structure, wherein the first siding product defines a frontal surface, and the frontal surface thereof defines a lateral channel therein, the lateral channel defining a plurality of channel walls including a lower transverse channel wall and an upper transverse channel wall, wherein the first siding product includes a downwardly opened connector on the frontal surface thereof, the downwardly opened connector having an upper first leg and a vertical second leg, the vertical second leg terminating in a terminal lower end, and wherein the lateral channel extends laterally between first and second ends of the first siding product, both the lower transverse wall and the upper transverse wall of the lateral channel being spaced vertically below the terminal lower end of the vertical second leg;
• aligning and connecting a second siding product with the first siding product by inserting a laterally elongated projection on a rear surface of the second siding product into the lateral channel on the first siding product;
• temporarily supporting the second siding product via a connection of the projection and the channel, wherein the temporary support is adapted to prevent the second siding product from falling, bowing, and sagging prior to installation of the second siding product on the structure;
• and
• installing the second siding product on the structure.
