The MB532YDB is a main bar curtain roller measuring 35.2mm in diameter and 31.9mm wide, designed to run smoothly along the main bar track of a curtain-sided trailer. It's stocked by LoadMonkey as a genuine-fit spare, ideal when the original roller has flattened or seized and is dragging on the curtain sheet.
Worth fitting in pairs if a neighbouring roller on the rail has also failed.
