PVC patio / balcony doors equipped with the new duoPort SK fitting system have both a slide and a tilt function and therefore enable attractive window solutions even in limited space.

Long-lasting comfort solutions
The benefits for the user include a high level of operating convenience, extremely quiet running and need-based burglary protection. The solid drive mechanisms of the duoPort SK system are fitted with 28 mm wheels, which enable the sash to slide smoothly and silently. Integrated cleaning brushes help maintain precise running. The low threshold height offers easy passage.

Two designs 
Winkhaus is offering the new slide-tilt fittings in two technical designs. With duoPort SK-S, the balcony door can be opened and closed manually both smoothly and safely. The duoPort SK-Z design offers added convenience: A handle control acts as a forced control here for easy tilt opening.

Sturdy technology for heavy sashes 
Reliable technology is invaluable when large, heavy glazing panels need to be opened and closed. The Winkhaus slide-tilt fitting system duoPort SK is optimally suited for such requirements. Load capacity of duoPort SK fittings: up to 200 kg sash weight depending on the design.

Modular burglary protection 
The duoPort SK fitting range can be very easily adapted to meet individual security requirements. Both basic and advanced duoPort SK system models feature solid mushroom-head locking bolts. The security keeps fitted on all sides enable burglary protection up to RC2/RC2 N to be achieved.
