A-Lok Products, Inc. was established in 1971 and evolved from the development of the A-Lok pipe-to-manhole connector. Industry demand for a watertight connection between pipeline and structure led to the original A-Lok seal design and to further development of an entire line of ecologically-responsive wastewater products, including flexible connectors for all applications, plastic inserts and seals for manhole entries and joints, manhole invert forming and corrosion resistant linings. 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.
