Abstract: A continuous casting mold cavity narrow faceplate taper gauge that includes a mounting bracket having a first portion with abutment feet for engaging a narrow faceplate of a continuous casting mold cavity and a second portion having a surface disposed at an angle to true horizontal that varies as a function of angle of the faceplate engaged by the first portion. An inclinometer is disposed on the surface of the second portion for providing an electrical signal that varies as a function of angle of the surface to true horizontal. An electronic display is responsive to such electrical signal for indicating taper angle of the faceplate engaged by the bracket.
