MB530BB is a genuine-fit main bar roller for HGV curtain-sider trailers, 35.5mm diameter x 30mm width, matching the original running gear on the main bar rail. This roller is part of LoadMonkey's range of replacement curtain gear for HGV, truck and trailer bodies, matched to the original dimensions for an easy fit.
