                                                                                                                                      1. 适用于欧标U 槽口12-20-9/13 系列塑钢型材；
                                                                                                                                      2. 五金接口标准化设计，可根据客户要求选择不同的配置方案；
                                                                                                                                      3. 该系统可实现窗扇悬开功能，满足用户微通风需求；
                                                                                                                                      4. 铰链三维可调便于窗户制作、安装、调节，承重级别取决于铰链，可参考铰链系列；
                                                                                                                                      5. 中间锁的使用，锁点均匀分布于窗扇四周，有效提高窗扇的密封性能；
                                                                                                                                      6. 防误操作器可承受较高力矩，有效防止错误操作执手对窗扇的损坏，提高安全使用性能；
꧒                                                                                                                                       7. 当窗扇宽度超过1300mm 时，须加第二斜拉杆。
