Carl F Groupco has released a new guide to support the outward opening window hardware from Roto.

The new document provides a clear and simple summary of Roto hardware suitable for different outward opening window styles, including FRH Reversible, Projecting, NT Tilt and Turn hardware and the TSL and SSL espagnolettes.

Carl F Groupco’s product manager Julie Warner said: “Products from the Roto range are regular top sellers for us so it’s important to highlight these products. The reversible range has been supplied by Carl F Groupco for 20 years and remains a market leader, and the PAS 24 tested TSL twin cam espag has proven to be a continuous best seller in our range.”
