AD 56303564 Polyurethane Rear Squeegee Set for Advance Captor 4800B, Nilfisk CR 1200B Riding Floor Scrubbers. This two blade rear squeegee kit consists of two yellowish-clear chemical, oil, and abrasion resistant polyurethane squeegees which are mounted on the curved rear squeegee assembly. The rear (outer) blade measures 71" x 3-3/4" with 15 total mounting holes. The front slotted (inner) blade measures 67" x 3-1/2" with 13 holes and 12 slots, 6 on each side. The polyurethane squeegee blade set is listed as an optional set. Polyurethane (Urethane) squeegees are a bit stiffer than the standard oil-resistant squeegees. These blades are used in areas with heavy greases and oils. They are also naturally chemical resistant and can be used where caustic chemicals exist. Polyurethane is also extremely abrasion resistant. These blades can be used in glass manufacturing facilities, bottling plants, or other areas where broken glass may be an issue. These can also be used on concrete sidewalks and similar abrasive surfaces. We offer the standard set, Premetek set (AD 56303472) and an oil and chemical resistant black neoprene set (AD 56303470).
