Bring natural light into the space below with a CRL walk-on rooflight. Correct fitting starts with an accurately measured opening, a properly prepared timber kerb and suitable drainage. Follow the downloadable fitting guide for the full installation sequence.

• Check your opening: The internal opening must match the ordered rooflight size exactly.
