기능

• This is an order-ready item.
• The bearing uses a rubber seal (airtight and dustproof) and has excellent water resistance.
• Can be used outdoors.
• Two bearings are used for the wheels, allowing even heavy doors to move smoothly.
• Since there is a gap between the frame and the wheel, even if there is some distortion or deviation in the rail, it can absorb the distortion and move smoothly.
• At the gate.
