This clay 450mm plain roll top decorative ridge from Marley comes in Red Smooth and is available in 105°. The plain roll top decorative ridge can be used with clay plain tiles but should not be used on rafter pitches below 35° with Acme double camber or Ashdowne handcrafted clay plain tiles. 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.
