As one of the standard accessories for the 50 series aluminum alloy sliding doors, it is fixed under the door against the wall, breaking away from the traditional setting of the sliding door track. Instead, it uses a joint guide structure of upper track suspension and lower guide wheel, with separate profiles and reserved holes for the door body during assembly, which are used as guide wheel tracks. When in use, the ground is first drilled with an electric hammer, and expansion bolts are inserted to fix the guide wheel. For irregular and uneven ground, square tubes can be filled under the guide wheel to guide and stabilize the door as a whole. The same groove wheel works together to maintain the stability of the door during the sliding process and sliding within the fixed track range.
