The door threshold brush supplied by Aoqun brush factory can be directly assembled on h-shaped, F-shaped, Y-shaped and some other special-shaped aluminum alloy bases; it can be fixed on the door body by drilling and pasting, and can be attached to the ground. It has a good sealing and dust-proof function. After installation, it can prevent 98.5% of the air from being lost. The adequate indoor air-conditioning will not "slide" away at the bottom of the door, and the outdoor hot air will easily "break" into the constant-temperature indoor space.

How can such a sealing effect be achieved? The trick lies in the brush filament of door threshold brush. It is made of pure nylon wool. The filament has high flexibility and good resilience. With the support of the process, it is not easy to deform and not shed. It can reach 1 million times from the experimental test. The back and forth friction still maintains the sealing effect, and the performance changes little.
