Robust UK, a UK manufacturer of steel door solutions, now offers adjustable head extensions free of charge on all non-certified doorsets on request.

This solution is designed to cover gaps of up to 15mm between the frame header and the structural opening. Unlike conventional solutions such as spacers and mastic that simply fill gaps, the adjustable frame header extension is designed to create a professional-looking installation.

According to Robust, the new adjustable header extensions reduce the risk of remakes or unsightly gaps following site survey mis-measurements or in the instance of particularly out-of-square structural openings.

Installation is simple and efficient thanks to the use of jacking screws, and each unit is manufactured so that it can be trimmed on-site to the exact required length.

Paul Williams, commercial director at Robust, explained:

“Our new adjustable head extensions provide installers and project managers with the ability to achieve an aesthetically pleasing finish to a doorset, even on challenging projects. It was developed in response to customer requests for a completely flexible solution, allowing customers to overcome any issues with mis-measurements up to 15mm between the frame header and structural opening.”
