The Taper-Lock Form saver brings together the Dowel Bar, Dowel-In Splicing System, and Taper-Lock technologies while also allowing for faster installation. It’s easy to use, requires fewer turns, and is fast to assemble. Once the form is removed, the Taper-Lock can be tightened by hand without any tools. This form saver can be used to reinforce concrete on bridges, parking garages, columns, and piers. Dayton Superior. 877-266-7732.
