The cove scriber is used to scribe lines on the felt for positioning the cove template. The cove template is used for scribing the inside cove pattern onto the vinyl. Afterward, the cove scriber can also be used to scribe the top edge onto the vinyl to fit the cap metal. Produces a cove to 3 3/8-inch standard height, but is adjustable for greater height if needed.
