Q: What does “nap” mean in this roller cover description?
A: “Nap” refers to the thickness of the roller’s fabric pile; a 3/8″ nap is suitable for smoother surfaces and allows controlled distribution of liquid coatings.

Q: Why are there uniform perforations in this roller cover?
A: The perforations allow liquid to pass through the roller cover, which helps when using sprayers or glue machines to distribute coatings or adhesives evenly.

Q: What is the significance of a heavy duty plastic core with 1½″ diameter?
A: A larger-diameter, heavy duty core provides rigidity and stability during high-speed equipment use, reducing flex or deformation under load.
