PERC Rotary Scrapers operate with the lowest clearance around the pipe, saving you excavation dollars and making work in tight conditions very easy. These scrapers peel a single continuous ribbon of material in preparation of coupling, tee, or branch saddle installation. The blade is 4 sided and spring loaded to float over ovaled pipe. The travel wheels are sealed ball bearings providing smooth even travel. 90% of the parts on the PERC Rotary Scrapers are interchangeable from 1.25” to 12”IPS making parts replacement and stocking easy.
