Quality Material: Our rollers are made of high quality copper and POM wheels, screws are made of 304 stainless steel. We intend our wheels to roll smoothly and reduce rusting in humid environments.
Works Great: After testing, every sliding door roller supports up to 66.14lbs, could prevent sagging when you move the door. POM wheels effectively reduce screeching noises and ensure a quiet usage environment.
Size: Wheel diameter-19mm, wheels thickness-5mm, inner hole-4mm, fixed with M4 screw. Please make sure you order the right size for your track system, thanks for your understanding.
Easy Installation: No professional skill needed, just put wheel at the mounting place, tighten the screws to fix it, at last put roller into the track and level the door.
