The Low Profile Rollers are for use with 4” to 20” (100mm - 500mm) pipe. McElroy’s rollers allow you to pull a string of pipe around a curve and over considerable distances. Pipe, and even the fusion joints, slide easily through the rollers and off the ground, keeping the pipe clean and increasing productivity. Easily paired with the PolyHorse and other McElroy products, the Low Profile Rollers are versatile, handy, and essential for projects that need high-performance pipe rollers to improve workflow.
