Private equity firm MiddleGround Capital announced the sale of Arrow Tru-Line, an independent manufacturer and supplier of structurally critical overhead garage door hardware components, to the Chamberlain Group, a Blackstone Portfolio company.

Chamberlain Group is a supplier 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. Major brands include LiftMaster and myQ.

Originally founded in 1970 and headquartered in Archbold, OH, Arrow Tru-Line manufactures a complete offering of essential hardware, including hinges, brackets, angles, tubes, springs and pre-assembled track sets through the processes of rollforming, stamping, assembling and sourcing products.

Arrow Tru-Line has a history of private equity ownership. Long Point Capital acquired the company in 2005 and Sun Capital Partners purchased the company in 2017. MiddleGround has owned the company since December 2021. The company, led by CEO Thomas Brockley, operates six manufacturing and distribution facilities across the U.S. and Canada.

Notable initiatives include automating production, upgrading digital infrastructure by implementing a new ERP system and vertically integrating spring and torsion tube manufacturing to reduce dependency on imports. They also executed margin expansion initiatives through price adjustments, SKU rationalization and vendor consolidation, according to the Sept. 9 news release.
