4. Pulley: Take the weight of each sliding door and window, and move it horizontally.

The pulleys used for sliding doors should use heavy-duty door pulleys instead of sliding pulleys.
Five and a half months locks: Most of them are hooks between fans and fans. Consumers should choose stainless steel or aluminum alloy.
6. Hinge: It is advisable to have a trifurcate hinge with high strength, strong load-bearing capacity, convenient disassembly, flexible opening and closing, silencer and other characteristics.
7. Sealing strip: Since the combination of the door and the door panel is hard and hard between the panels, the instantaneous noise of closing the door is as high as 120 decibels, which seriously affects the physical and mental health. The use of high-strength weatherstrips does not react with the paint, ensuring smoothness of the paint. And it also has shock absorption, noise reduction, sealing, sound insulation, moisture and other characteristics.
