DS12 and DS36 are made entirely of steel that is zinc plated for corrosion resistance and toughness. Reed produces a line of competitively-priced, heavy-duty power transmission belting pipe descalers (DS12B, DS36B). Handles and scrapers for the belt descaler line are blackened for good rust protection. Benefits from belt descalers include lighter weight than chain descalers, plus much longer length to ease back strain. High profile scrapers on the belt descalers dont get clogged with dirt. Reed-style roller handles allow greater comfort in use. Also, belts with attached scrapers are available as replacements. These replacement belts also fit Wheeler belt descaler handles
