Set of 4 Dia 19mm Stainless Steel Shower Door Wheels Rollers Runners, White, 19mm x 5mm (Stainless steel-4PCS)
These replacement shower door rollers (4-pack) are designed for 19mm wheels with 5mm thickness, intended for sliding glass shower doors 4–6mm thick. Buyers generally report smoother, quieter rolling and easy installation, with the main caveat being that the included screws may not match every door hardware setup.
