The scalloped felt blade insures airflow and collection of even fine particulate without the risk of brimming debris like some floor brushes. The felt blades are static neutral making them ideal for vacuuming flowing floor surface refinishing. Ideal for use with major brands of commercial backpack vacuums using 1.50” accessories including Pro-Team, Mosquito, Tennant, Powr-Flite, Hawk, Sanitaire, Rubbermaid, NSS, Mercury, Sandia, and Nilfisk. The 60137 is compatible with major brands of commercial canister vacuums including Powr-Flite, Hawk, Nilfisk, Karcher, NSS, Mercury, Sanitaire, Tennant, Nacecare, and Pacific Floor. Also excellent for brands of vacuums typical in the hard floor refinishing business like Pulse Vac, IPC, and Cen-Tec's Elsea line.

Setting the length to the user ensures maximum productivity is realized when using the double pivot neck design of the Sidewinder nozzles
