  • The wheel sliding door roller system is a testament to engineering excellence. It consists of a set of wheels mounted on a bracket, which attaches to the bottom or top of the door panel. As the door is pushed or pulled, these wheels roll along the track, ensuring a smooth and noiseless movement. The precision engineering of these rollers minimizes friction, making it easy for even the heaviest of doors to move with minimal effort.
