When it is necessary to bend the mono-rail in the field, the Prima mono-rail bending tool makes it easy to apply a smooth and even curve to the rail.  Curves should be limited to a 6" minimum radius.  Vertical bends are not recommended.  Full circles, "S" shapes are easily accomplished with the bending tool.
All Prima track systems are 12 volts and require a transformer (sold separately - see accessories); use of components not sold by Prima may void the warranty.
