Coreline Rollers, an M7 Holdings Company, Launches with National Reach from Two Manufacturing Plants

AKRON, Ohio, Aug. 26, 2026 - M7 Holdings today announced that two of its manufacturing businesses, Harwood Rubber Products of Cuyahoga Falls, Ohio, and Rubber Right Rollers of Chelsea, Massachusetts, have united under a single brand: Coreline Rollers. The launch completes an integration that began in December 2025, when Harwood acquired Rubber Right, and gives the combined company a manufacturing and service footprint spanning the Midwest and the Northeast.

For M7, the more significant story is the arc that led here. Both businesses were second-generation family companies with long customer relationships, deep technical knowledge, and owners ready to step back. Harwood, with 65 years of history, joined the M7 portfolio in December 2023. Rubber Right, founded in 1992, was acquired by Harwood in December 2025. Now, the two operate as one company under one name.
