Leinfelden-Echterdingen – (rp) Roto has announced a reinforcement certified in accordance with QM 328 for the universal “AL 540” hardware range suitable for aluminium windows and balcony doors up to 300 kg. The company explained that with the market launch of a surface-mounted hinge side for Euro-chamber profile systems the range now covers sash weights up to 160 kg. At the same time, this increases the application range for floor-to-ceiling elements up to a sash height of 2,700 mm.
This innovation will initially be available for the Turn-Only / Tilt&Turn and TiltFirst opening methods. Turn-Only and dummy mullion sash versions are in the pipeline The hinge-side components, in combination with the “AL 540” central locking system, also enable efficient burglary protection to be provided, up to RC 3 in accordance with DIN EN 1627 – 1630. Apart from this, the optional accessories ensure that “even the most demanding of tenders” can be realised. The absorbing function of the maintenance-free, damped turn restrictor serves to relieve the hinge side.
The sash stays for use in the left and right hinge side versions with stainless-steel rod come with a 190 mm tilt depth. According to Roto this provides a larger ventilation capacity coupled with a particular suitability for profiles with special installation depths. The latter is required, for example, in aluminium window systems certified for passive houses. The stay bearing with counter bearing can be connected to an additional connecting-link attachment. The construction supplier rounds off its brief portrayal of the hardware innovation with a reference to the pivot rest with additional screw and the reinforced corner hinge.
