The cover measures 4.5 inches wide with a 3\/4-inch nap, making it suited for semi-rough surfaces where consistent film build is needed. Constructed with a golden yellow fabric exclusive to Wooster, the cover resists matting during application, which helps maintain even coverage and reduces the need for multiple passes. The 3\/4-inch core design simplifies post-job cleaning and keeps refill costs down compared to larger-format covers. Painters, maintenance technicians, and coating applicators will find this cover a practical choice for production-volume roll work.\u003c\/p\u003e\n\u003cp\u003eThis roller cover is intended for use on semi-rough surfaces such as textured drywall, light stucco, and similar substrates. It is compatible with all Jumbo Koter cage frames, making it a direct drop-in refill for that frame system. The 4.5-inch width is well suited to trim work, cabinet faces, doors, furniture, and narrow panel sections where a full-size 9-inch roller would be unwieldy. The 2-pack quantity reduces downtime on multi-surface jobs by allowing a fresh cover swap without stopping to clean mid-project.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-inch width with 3\/4-inch nap for semi-rough surface coverage\u003c\/li\u003e\n  \u003cli\u003eGolden yellow fabric construction exclusive to Wooster resists matting\u003c\/li\u003e\n  \u003cli\u003eCompatible with all Jumbo Koter cage frames for easy refill swaps\u003c\/li\u003e\n  \u003cli\u003eWorks with flat, eggshell, satin paints, stains, and waterproofing products\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch core simplifies cleaning and lowers per-use refill cost\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-pack for extended job coverage without interruption\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any Jumbo Koter cage frame.

Ensure the cover is secure and does not slide laterally during use. After use, remove the cover from the frame before cleaning to prevent water or solvent from entering the frame bearings.
