Products: Dampening Covers: Cotton Products

When we introduced a brand new tubular-knit material way back in 1938, we started a revolution. The future of seamless dampener covers had begun. And since then, we've improved and expanded our line of pure cotton products to the point where it's easily the largest and best available. For many of our customers, only a genuine Jomac cotton cover will do. Rest assured that the legendary quality that helped build our worldwide reputation will continue to be built into every roller cover we make.
