The McElroy 28 fusion machines will butt fuse pipe sizes from 2" IPS - 8" DIPS (63mm - 225mm). They come in multiple model configurations to assure your pipe fusion needs are covered.
Rolling, TracStar® and Pit Bull® machines incorporate the interchangeable 28 four-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. Several of these units offer saddle fusion capability in the form of a Combination Unit (CU) that allows fusion of branch saddle with a maximum base diameter of 9.63" onto any size main.
