Why Wooster?

Wooster's Painter's Choice line keeps roller covers like the R337-9 consistent in fabric and nap so crews can standardize on a known size, 9" with a 3/8" nap, across jobs. The knit fabric construction is carried over exactly as cataloged, so each R337-9 you buy matches the last one you used. Buying it sold as each keeps restocking simple when you just need to swap in a fresh knit fabric cover rather than ordering a larger multi-pack. Each roller cover ships ready to load with your preferred paint, so there's no unexpected substitution in fabric or nap size when you reorder.
