Racing Window® allows you to select as an option between three models of sliding hatches during the process of setting up and purchasing your windows. The default option provided that none of these three models is selected will be "No trapdoor".
The design of these three models correspond to the following images, which in descending order are: straight trapdoor, inclined trapdoor and curved trapdoor. All our hatches have a spring system for locking them in the maximum opening and closing positions.
Racing Window® outside these standard models allows you a series of customization options that reach to achieve completely exclusive and customized designs for your project. For all these options, contact us directly.
