Manual Side Roll
The Roll Master System is a simple, one-step Roll & Lok tarp system—no ratchets, straps, or tiedowns—for all applications. Anchored by an aluminum lok rail that can be installed on the driver or passenger side, Roll Master manual side roll tarp systems come standard with 18 oz vinyl tarp, aluminum square front and rear caps, standard tarp stops, splined crank assembly, and front return assembly. All hardware is made with aluminum or steel-plated parts, and our standard width roll tarps are one piece: seamless, smooth, and straight, for years of trouble-free service.

We offer complete manual roll master tarp systems for open top vans and semi grain tailers, from 30’-32’ trailers through to 50’-52’ trailers.
