Abstract
A segmented sliding sill wear plate for universal application to fit a variety of installations and which includes a metal base plate having a plurality of low friction plastic pads bonded to the plate in spaced apart relation, wherein a single long wear plate with multiple pads can be made without warping and can thereafter be cut to size and suitably secured to a sliding sill support member such as by welding or by fastening devices. Because of the size of the plastic pad, a wear plate cut to size can withstand a wide range of temperatures without causing delamination of the plastic material or warping of the metal base.
