Easy to Install
Our modular pivot was designed to make your job easier. We have pre-assembled our parts into a compact, self-contained package, making installation easier, quicker and more economical.

Easy to Operate
In 1993 our engineering staff discovered the secret for consistent controlled arm movement. Since then many companies have tried to imitate, but none have uncovered our secret for providing smooth automatic operation.

Easy to Maintain
The Magnum was engineered to be tough, reducing repairs. Arm deflectors and a lower profile design helps keep containers off the arms, avoiding damage, saving you time and money. We have routed the hydraulic hoses inside the arms for added protection. This compact unit makes routine truck maintenance more accessible. The stabilizer offset and heavy gauge construction guarantees your tarping system will hold up under the stress of the real world.
