Why Clay Fittings All clay fittings can be used with clay plain tiles, keeping that authentic roof look. Clay plain tile ridge tiles are a key example that can be attached to clay fittings because of their security ridge straps. In turn, this means little need for long searches for a fitting that can match expectations. Clay roof fittings can also be decorative or plain depending on the purpose of your property.
