Abstract: A shim for use with a wear member comprises a body that defines a first aperture that includes a closed end and an open end, wherein the first aperture is defined by at least three surfaces including two side surfaces and at least one surface that defines the closed end and that further defines a surface normal that points toward the open end, and a second aperture that includes a closed end and an open end, wherein the second aperture is defined by at least three surfaces including two side surfaces and at least one surface that defines the closed end and that further defines a surface normal that points toward the open end. The surface normal of the first aperture forms an angle with the surface normal of the second aperture that is greater than zero degrees.
