In addition to the hanging rail, the other important accessory of the glass sliding door is the hanging wheel, and the material and workmanship of the hanging wheel determine the service life of the sliding door. Then we can refer to the 423-4B glass door hanging wheel of Lelang Hardware. The hanging wheel body is full of material and fine workmanship. It is made of zinc alloy die-casting surface. The wheel bearings are imported from Japan. After testing, the running speed is fast and the number of uses high. One of the important problems of the glass sliding door is mute, and the 423-4B glass door hanging wheel also takes this problem into account, so the wheels are made of high-quality nylon material, which is more silent and durable when used.
