The Rolling 250 was designed in response to international metric pipe needs and is based on the popular Rolling 28, which has been the industry standard for more than 40 years. Features include an interchangeable 4-jaw carriage, which can be easily removed for in-ditch fusion. For tight installations, the outer fixed jaw and skid can be removed from the carriage converting it to a 3-jaw carriage for an even more compact fusion unit. It also is available in a Combination Unit (CU) for sidewall fusion and is DataLogger®compatible.
