Robust UK, one of the UK’s leading manufacturers of steel door solutions, now offers adjustable head extensions free of charge on all non-certified doorsets on request.
This innovative 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 creates a professional-looking installation, every time, enhancing the overall appearance.
Fitters will welcome the fact that the adjustable extensions for door headers avoid the need for frame packers, and dispensing of the need for mastic will also ensure a more aesthetically pleasing result for the end customer.
Ultimately, Robust’s 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, supporting smoother project delivery and avoiding unnecessary cost.
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, ensuring a precise finish every time.
Previously, gaps of up to 10mm would have required filling with mastic, a process that could delay projects, look unsightly, increase costs and often involved specialist trades. Robust’s new adjustable header extensions eliminate these issues and increases the gap tolerance by 5mm, allowing fitters to complete installations quickly and efficiently while maintaining a high-quality finish.
Paul Williams, Commercial Director at Robust, explains: “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.”
Robust is always seeking to innovate and offer its customers new solutions that meet market demands. The new adjustable door header extensions are the latest innovation that is set to resolve issues for door installations and ensure greater customer satisfaction. This development is just one of many upcoming product innovations following a £6 million factory investment in 2024, as Robust continue to refine and expand their product and solution offering.
