A "Four Cut Corner" cover can be either square or rectangular. Be sure the measurement specified for Y is also parallel to the direction of the hinge! Dimensions for the cut corners will be specified in steps 3 and 4 below. If all four cut corners (Z) are NOT the same, we will require a diagram to make the cover.
|In some cases it may be difficult to measure
diagonal Z and may be easier to determine Z
based on the picture and chart below.
