To properly support, position and align the pipe to be fused. We also have hydraulic piping bases. Supports can be positioned at intervals from the fusion machine down the pipe, creating a track that allows the fused pipe to slide through the rollers. This is especially useful on projects that require contractors to keep the pipe clean and off the ground. Low profile rollers and rollers MegaMc® allow curving for long distances. All McElroy tube rollers are tip-resistant and minimize the force required to drag the slings of tubing.
