A "One 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! It's important to choose either A or B depending upon the hinge configuration. The diagonal cut, Z, will be specified in steps 3 and 4. If the three uncut corners are rounded, please specify the radius in the special instructions section.

 
In some cases it may be difficult to measure the
diagonal Z and may be easier to determine Z
based on the picture and chart below.
