These rooflights are supplied as a GRP 175mm kerb and a predrilled glazing unit allowing the installer to screw fix the glazing to the kerb. The pre-drilled fixing holes are positioned using state of the art cutting technology,ensuring a reliable and accurate fit every time.

Once installed,security caps encase the fixings for additional security. The security caps are designed to improve waterproofing and reduce the likelihood of forced entry through the rooflight. The security caps are extremely difficult to remove after installation.
