The door roller position can be adjusted according to the width of the door frame, and the door roller guide rail is made of bearings and white zinc, which better reduces friction and noise, making your sliding door run smoother and quieter. White zinc is an anti-corrosion treatment that prevents rust and corrosion by coating the metal surface with a layer of zinc. This treatment can make the product more durable, especially in outdoor environments. The universal L-rail mounting bracket is suitable for all sliding door types and can be mounted facing up or down depending on your specific assembly needs. It offers versatile compatibility for a variety of sliding door setups. With high bending resistance, it ensures strong support for your automatic slid.
