This rear squeegee blade is made from urethane and fits the NSS Wrangler 1503 floor scrubber. Urethane is softer than Linatex, giving it good contact across all floor surfaces, and it holds up well against oils, making it a strong choice for kitchens and automotive shop floors. It replaces the factory rear blade to restore a clean, even wipe as the machine works. Pair with the matching front urethane blade for full squeegee coverage.
