NEW YORK: Allegion plc, a global security products and solutions provider, has acquired privately held Overly Door Company, the company announced.

Overly, founded in 1888 and headquartered in Greensburg, Pennsylvania, manufactures custom specialty doors for acoustic, blast, bullet-resistant and vault security applications. The company serves commercial and institutional customers, with particular strength in U.S. government, education and healthcare markets. Its products complement Allegion’s existing hollow metal doors and frames portfolio.

Overly will operate as part of Allegion’s Americas segment, led by Senior Vice President Dave Ilardi.

“Overly is a great addition to Allegion, bringing another century of experience, talented experts and a specialty portfolio aligned with what we’re known for—making critical, complex environments more secure and accessible,” Ilardi said. “Together, we will specify and supply a broader range of custom door solutions across core non-residential markets.”

Overly leaders Tyler and Jonathan Reese will join Allegion to support a smooth transition.

“Overly has built its reputation on uncompromising quality and service in high-security markets,” Jonathan Reese said. “We share that same commitment with Allegion, and we’re confident our combination will drive new value and greater efficiency for our operations and our customers.”

Terms of the transaction were not disclosed.

Allegion, based in Dublin, Ireland, designs and manufactures security and access solutions under brands including CISA, Interflex, LCN, Schlage, SimonsVoss and Von Duprin. The company reported $4.1 billion in revenue in 2025.
