ThruLOK® is a secure way to attach deck posts and carrying beams. and is much easier to install than a traditional carriage bolt, nut and washer. The traditional installation method requires a drill, drill bit, hammer, and wrench for install. ThruLok®, however, only requires a high torque variable speed 1/2″ drill. The ThruLOK® system combines the speed of a LOK product with the strength of a through-bolted connection in two decking applications: Single 2″ x 4″ board to a 4″ x 4″ decking post (6 1⁄4″), and two 2″ x 4″ boards to a 4″ x 4″ decking post (8″). ThruLOK® works on all types of pressure treated wood.
