Established in 1888 and based in Greensburg, Pennsylvania, Overly manufactures custom specialty doors for acoustic, blast, bullet-resistant and vault security. Overly solutions serve commercial and institutional customers, with strength across U.S. government, education and healthcare markets. Its product offerings complement Allegion’s existing hollow metal doors and frames portfolio.

Overly will operate as part of the Allegion Americas segment, led by Allegion 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 for the business.

“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.”
