I have been asked by friends to increase the clearance for a larger Refrigerator, this will require cutting almost 1" off of bottom of cabinet and one side. My question is remove doors and clamp guide rail to cabinet or take the cabinet down and cut it. Have any used the TS55 in his manner on the side of a cabinet? I will need to add some stiffening material to compensate for what I will be removing on the front. Thanks in advance.
