The Rebar-Lok centers rebar in the core of 8- or 12-in. masonry block in CMU walls after the wall is constructed and rebar is inserted. It guarantees a properly located bar, eliminating the need for low-lift grout, and accurately marks each grout hole. When engaged, the Rebar-Lok will tie and center overlapping rebars together if desired or just center the one bar in place. It eliminates excessive overlapping, and reduces the amount of labor needed when building without the Rebar-Lok. Polylok Inc. 888-765-9565. www.polylok.com
