Patent ID: 8231189

Claim:
An undermount drawer slide, comprising: a singular first rail including a vertical first wall, a first installation section and a second installation section offset each from the other disposed on the first wall adjacent respective opposing ends thereof, the first installation section having a first vertical distance measured from the center of the first installation section to a reference level on the first wall, the second installation section having a second vertical distance measured from the center of the second installation section to the reference level, the first vertical distance being different from the second vertical distance to form a height difference, D 1 , configured to provide a front to back downward inclination of the drawer slide when mounted to a fixed structure, and a second rail slidable linearly with respect to the singular first rail, the second rail including a top wall having a first end and a second end opposite to the first end, a protrusion disposed proximate the installation section having the greater vertical distance from the center of the installation section to the reference level on the first wall, the protrusion is disposed adjacent the first end of the top wall of the second rail, the protrusion having a height, D 2 , measured from the top wall which is formed substantially equal to the height difference, D 1 , between the first installation section and the second installation section to incline a drawer mounted on the top wall of the second rail in a direction opposite to the downward inclination of the drawer slide and thereby compensate for inclination of the drawer slide.
