╬ Window opener
The window opener can open the ventilation window at a higher position through a certain device. The window opening actuator determines the width of the window, the weight of the window opener and whether there is a locking function. The corner connector is a transmission component, and its deformation determines the ability of the window opener to adapt to different window types and different installation conditions. The operating component can be in the form of a handle or a rocker. There is also a manual window opener, which is suitable for hanging inside and top hanging outside windows.
🚪 Door closer
Door closers can be divided into three categories: door bottom springs, door top door closers and floor springs. The main feature of the door closer is that it closes slowly and there is no collision sound after closing. It is suitable for the doors of high-end hotel rooms. The door closer is divided into horizontal and vertical types. The function is equivalent to double-spring hinges, which can make the doors and windows automatically close after opening.
🔗 Hinges
Hinges are divided into two materials: all copper and stainless steel. When choosing hinges, in order to open easily and without noise, it is better to choose hinges with ball bearings in the middle axis. When choosing, the brightness of the paint and electroplating on the surface, the gap and strength of the load-bearing wheels determine the flexibility and noise of the drawer opening and closing. Wear-resistant and uniformly rotating load-bearing wheels should be selected.
🚪 Handles
The shapes and colors of the handles are varied.

The so-called latch is a set of pins used to fix the workpiece on the fixture or mold. It is a simple component to prevent opening. It is an anti-theft component to prevent doors and windows from being opened from the outside. The structure is much simpler than the lock. The lock is outside the door and the latch is inside the door.
