MiddleGround Capital has agreed to sell Arrow Tru‑Line, a manufacturer of overhead garage door hardware, to Chamberlain Group, a portfolio company of Blackstone.

The company’s manufacturing capabilities include roll forming, EDM machining, stamping, CNC milling, powder coating, plastic injection molding, and aluminum, zinc, and iron die casting.
Arrow Tru-Line is led by CEO Thomas Brockley and operates five manufacturing and distribution facilities in Ohio, Texas, Minnesota, Nevada, and Ontario. The company, founded in 1970, is headquartered west of Toledo in Archbold, Ohio.
Arrow Tru‑Line has a long history of private equity ownership. In 2005, the company was acquired by Long Point Capital from privately held Collier Spring Manufacturing. Long Point later sold the business to Sun Capital Partners in 2017. In December 2021, Arrow Tru‑Line was acquired by MiddleGround Capital through its inaugural fund, MiddleGround Capital I LP. The announced sale to Chamberlain Group marks MiddleGround’s third full exit from that fund, which closed in August 2019 with $460 million in commitments.

“MiddleGround has been an exceptional partner for Arrow Tru-Line,” said Mr. Brockley. “Their operational expertise and deep, hands‑on experience has positioned us with several competitive advantages. We’re looking forward to continuing the strategic momentum MiddleGround has imparted under the Chamberlain Group.”
Chamberlain Group is a provider of access control and smart home technology products, including garage door openers, gate operators, and commercial access systems used by residential consumers, commercial property managers, and automotive OEMs. The company’s key brand names include LiftMaster, Chamberlain, and myQ.
