The body may be movable between an uninstalled position, which defines a first offset along the longitudinal length and a second offset along the transverse width, and an installed position, which substantially closes the first offset and the second offset. In the installed position, the body abuts the mounting surface and an underside of the body is substantially planar. The tile may also include a plurality of first-angle ribs and a plurality of second-angle ribs. The first-angle ribs are offset relative to a forward edge of the body. The second-angle ribs offset relative to the forward edge of the body and also to the first-angle ribs. Furthermore, the first-angle ribs and second-angle ribs do not have shared vertices. ## Claims ### Claim 1 A tile for attachment to a mounting surface, comprising: a body defining a longitudinal length and a horizontal width in a single, continuous component, and having a forward thickness at a forward edge a rearward thickness at a rearward edge, wherein the forward thickness is greater than or equal to the rearward thickness, wherein the body is movable between an uninstalled position and an installed position, such that: in the uninstalled position, the body defines a first offset along the longitudinal length between the body and the mounting surface, and a second offset along the transverse width between the body and the mounting surface; and in the installed position, the body is biased against the mounting surface by a fastener to substantially close the first offset and the second offset, such that the body abuts the mounting surface and an underside of the body is substantially planar. ### Claim 2 (depends on 1) The tile of claim 1, wherein the first offset along the longitudinal length is greater than the second offset along the transverse width. ### Claim 3 (depends on 2) The tile of claim 2, wherein the body further includes: a plurality of first-angle ribs at a first offset angle relative to the forward edge; a plurality of second-angle ribs at a second offset angle relative to the forward edge, wherein the second offset angle is different from the first offset angle. ### Claim 4 (depends on 3) The tile of claim 3, wherein the first-angle ribs and the second-angle ribs join to form a plurality of radial intersections. ### Claim 5 (depends on 4) The tile of claim 4, wherein the first-angle ribs and the second-angle ribs cooperate to substantially define a plurality of elongated diamonds, and wherein the first-angle ribs and the second-angle ribs substantially contact the mounting surface in the installed position. ### Claim 6 An injection-molded tile for attachment to a mounting surface, comprising: a body having a face side opposite the mounting surface and an underside adjacent to the mounting surface; a plurality of first-angle ribs formed on the underside of the body at a first offset angle relative to a forward edge of the body; and a plurality of second-angle ribs formed on the underside of the body at a second offset angle relative to the forward edge, wherein the first-angle ribs and second-angle ribs do not have shared vertices and the second offset angle is different from the first offset angle. ### Claim 7 (depends on 6) The injection-molded tile of claim 6, wherein adjacent first-angle ribs are not collinear, and wherein adjacent second-angle ribs are not collinear ### Claim 8 (depends on 7) The injection-molded tile of claim 7, further comprising: a plurality of filleted intersections joining the first-angle ribs and the second-angle ribs. ### Claim 9 (depends on 8) The injection-molded tile of claim 8, wherein the first-angle ribs and second-angle ribs substantially contact the mounting surface when the tile is installed to the mounting surface. ### Claim 10 (depends on 9) The injection-molded tile of claim 9, further comprising: at least one longitudinal rib extending from the forward edge toward a rearward edge, wherein the longitudinal rib substantially contacts the mounting surface when the tile is installed to the mounting surface. ### Claim 11 (depends on 10) The injection-molded tile of claim 10, wherein the longitudinal rib extends substantially to the rearward edge of the tile. ### Claim 12 (depends on 11) The injection-molded tile of claim 11, wherein the first-angle ribs and second-angle ribs extend substantially to a left edge of the body and substantially to a right edge of the body. ### Claim 13 (depends on 12) The injection-molded tile of claim 12, wherein the body is movable between an uninstalled position and an installed position, such that: in the uninstalled position, the body defines a first offset along a longitudinal length between the body and the mounting surface; and in the installed position, the body is biased against the mounting surface by a fastener to substantially close the first offset, such that the underside of the body abuts the mounting surface. ### Claim 14 (depends on 13) The injection-molded tile of claim 13, further comprising: an offset injection point, wherein the offset injection point is not on a centerline of the body. ### Claim 15 (depends on 6) The injection-molded tile of claim 6, further comprising: a plurality of filleted intersections joining the first-angle ribs and the second-angle ribs. ### Claim 16 (depends on 15) The injection-molded tile of claim 15, further comprising: at least one longitudinal rib extending from the forward edge toward a rearward edge, wherein the longitudinal rib substantially contacts the mounting surface when the tile is installed to the mounting surface. ### Claim 17 (depends on 6) The injection-molded tile of claim 6, further comprising: a plurality of longitudinal ribs extending from the forward edge substantially to a rearward edge, wherein the longitudinal rib substantially contacts the mounting surface when the tile is installed to the mounting surface, and wherein the first-angle ribs and second-angle ribs extend substantially to a left edge of the body and substantially to a right edge of the body. ### Claim 18 An injection-molded tile for attachment to a mounting surface, comprising: a body having a face side opposite the mounting surface and an underside adjacent to the mounting surface, wherein the face side is textured; and an offset injection point, wherein the offset injection point is not on a centerline of the body. ### Claim 19 (depends on 18) The injection-molded tile of claim 18, further comprising: a textured injection area surrounding the offset injection point, wherein the textured injection area has a textured surface, which is not smooth, on the face side of the body.
