The 7CRBM 7" paint roller features a 100% polyester refill that is solvent resistant against various types of paint. The knitted production procedure creates a 15mm refill pile for smooth and efficient application. With a 48mm inner diameter and PVC stoppers at both ends, frame rotating blockage is avoided. The soften virgin PVC handle includes an 8mm frame rod and 5 zinc wire for secure refill locking.
