The 4" width is a mini-plus roller -- cabinet fronts, shelves, small doors, and confined areas where the 3" is too small and the 9" is too big. Fits standard 4" mini-roller frames. Jen Poly-Roller is an economical throw-away roller made from patented urethane foam. Lays down thin, even coats with less spatter than nap rollers -- ideal on smooth non-porous surfaces where a nap texture would show.

• Patented urethane foam roller head
• Compatible with enamel, latex, oil-based paints, stain, and varnish
• Less spatter and cleaner finish than nap rollers on smooth surfaces
• Fits all standard 4" roller frames
• Throw-away construction -- no cleanup required
• Ideal on smooth non-porous surfaces (metal doors, cabinets, trim)
• Width: 4"

Best For: Cabinet fronts, shelves, small doors, closet interiors, and mid-scale finish work where the 3" mini would be slow and the 9" would be unwieldy.
