What Zero International Inc. does
Zero International Inc. is a U.S.-based manufacturer of door sealing hardware, founded in 1924 and headquartered in Bronx, New York. The company produces thresholds, automatic door bottoms, perimeter seals, weatherstripping, intumescent fire-rated seals, sound control products, and specialty sealing solutions for commercial and institutional doors. It operates as a wholly-owned brand within Allegion's commercial family of brands, and its products are distributed globally through Allegion's authorized commercial door hardware distributor network alongside sister brands such as Schlage, Von Duprin, LCN, and Falcon.
The product portfolio is organized into two tiers: Zero Preferred, a premium line built for high-demand, high-traffic spaces such as schools, hospitals, and universities, and Zero Everyday, a practical and affordable line for apartments, hotels, retail, and offices. Zero International sells primarily to vertical markets including K-12 education, higher education, healthcare, multifamily, government, and general commercial, with applications spanning fire-rated assemblies, ADA-accessible thresholds, acoustic privacy, and energy-efficient green building envelopes.
Because Zero International is structured as a sub-brand of Allegion rather than a standalone reporting entity, its revenue is not separately disclosed and its headcount is reported at approximately 10 employees. Pricing is quote-based through Allegion's distribution network, and the company's go-to-market depends on architect and contractor specification, supported by Allegion's shared services in architectural consulting, code and compliance coordination, and technical support.
