Anthony Innovations’ vast range of sliding door rollers for external doors are developed with functionality and durability in mind. Designed with either two or four wheels, these heavy-duty sliding door rollers are ideal for both high-end residential and commercial application. As technology and design evolve low sightline window and door panels and accompanying heavy-duty door rollers are becoming more popular. To complement sliding door designs that maximise outdoor views and natural light, our range includes both sill-mounted rollers which are easy to replace, and rail-mounted rollers ideal for environments with high levels of debris and contamination. Our roller assemblies are composed of a diverse range of materials to suit different environments. All sliding door wheel carriages have undergone rigorous testing to ensure longevity, durability and reduced rolling resistance.
