Solid Build — Stamped steel wheels with yellow zinc plating. Resistant plastic rollers that glide smooth, last long, and run quiet. Narrow recessed edges keep everything tracking right. Check Your Specs — 1-1/2" concave nylon wheels, 2-1/2" mounting hole height. These numbers matter. Double-check before you buy so you don't end up with the wrong fit. Fix That Sticky Door — Swap out worn rollers and get your door sliding like new again. Less track wear, no more catching or jumping off the rail, and your closet door lives longer. Easy to Put On — Bottom-mount design for sliding mirror doors. Tab fits the door frame, rear lip holds the roller assembly steady. Adjust height with the center screw. Slotted metal bracket comes off separately when you need it. Works on Most Closet Doors — Wooden rollers, metal-framed mirror doors, contractor-grade setups—if your sliding door's sticking or popping off track, these rollers handle it., Manufacturer: LuLobtg
