The BOB36G is a solid bobbin, 35.8mm diameter x 35.8mm width, fitted along the curtain rail of an HGV or trailer curtain-sider to guide the sheet as it runs. LoadMonkey supplies this part to keep curtain-sider fleets moving, swapping out tired bobbins before they start marking the sheet.
Worth keeping a couple as spares if your fleet runs several curtain-sider trailers.
