Expanded application range of “Roto AL” / New Turn-Only hinge for Top-Hung and Side-Hung windows / Equipped to meet special requirements in outward opening windows / Proven technology for windows that remain reliable in the long term.
Since Turn-Only hinges on outward opening windows are exposed to the weather, Roto has made the new “Roto AL” Turn-Only hinges weatherproof and UV-resistant. For instance, the pivot support bushes in the Turn-Only hinge are made from UV-resistant and weatherproof PVC, which also has optimum sliding properties.
The new “Roto AL” Turn-Only hinge for outward opening Top-Hung and Side-Hung windows therefore ensures functional safety for a long window service life. It is screwed into the sash and also into the frame. This allows even high tractive forces to be handled.
Threaded pin protects against external access
The “Roto AL” Turn-Only hinge for outward opening Top-Hung and Side-Hung windows has a threaded pin, which prevents the bearing pin newly developed for this application from being removed from the outside. The threaded pin can only be loosened when the window sash is open, which means that unauthorised access by third parties is impossible.
