    A 90-degree opening of the door is sufficient. Only in exceptional cases does it need to be opened 180 degrees.

In terms of product performance and comfort, the performance of Wang Li's products is better than that of Buyang for the same type of door, because Wang Li's door locks and hinges are designed and produced by themselves, and the cooperation with the door is more reasonable. From the construction of service outlets, Buyang's outlets are more than Wang Li, that is because Buyang's sales policy is better, attracting a large number of dealers, Buyang's annual sales are about 2 times that of Wang Li (Buyang's sales in the last year were 2 million doors), the price and style are your own consideration and comparison. I'm looking at the big picture. >>>More
