In 1990, Builder's Best® had a simple mission: manufacture The All Metal Solution to Dryer Venting™. Easy to install, but a fire hazard, slinky dryer vents were clogging up dryers nationwide. A new way of hooking up clothes dryer venting was needed. Charles Anderson had an idea for venting that could be installed in close quarters and allowed the dryer to be pulled away from the wall without disconnecting the system. His solution was the Snap-Lock™ Pipe and Close Elbows™. Builder's Best quickly gained recognition for its unique solutions, including more elbows and rigid periscopes, redefining efficiency and safety standards.
