Lenton Lock, a new in-situ rebar splice, requires no bar-end threading. It is ideal for new construction, repair or retrofit applications. The Lenton Lock coupler features patented gripping technology that provides for the development of full rebar strength and improved overall structural integrity in tension, compression, stress reversal and dynamic applications. This mechanical rebar splice is designed to specification for use in column splicing, bridge applications, piling, splicing to protruding dowels cast in concrete, closure pours, beams, chimney construction and other demanding splicing applications.
