A-Lok is committed to working closely with customers as part of the research and development process and, with the support of talented human resources and a commitment to innovative design, superior craftsmanship and outstanding customer service, the A-Lok name is synonymous with watertight quality in underground structures throughout North America. 3956 Mogadore Industrial Parkway Mogadore, Ohio 44260 Phone: 330.628.6230 Fax: 330.628.6231 www.vertexseals.com Vertex, Inc. established in 1992.
