The new Smart DI+ design reduces the amount of force required to set the anchor. What used to take about 20 hammer blows on a typical 3/8-in.-diameter part can now be accomplished in approximately five blows, thus reducing overall labor costs by approximately 50 percent, according to the manufacturer. The cylindrical plug design concentrates more expansion at the bottom of the anchor where it’s needed to maximize performance.
Mechanical and electrical contractors use drop-in style anchors to hang threaded rods from ceilings to run pipe supports, fire sprinklers, cable trays and strut. Concrete contractors use them for temporary form work. Installation can be completed in three steps: drill the hole with Smart DI+ Bit, lock on the Smart DI+ setting tool, and drive the plug with the same tool used to drill the anchor hole. — Powers Fasteners Inc., 800/524-3244; www.powers.com
