SimpleSox™ is a fabric HVAC duct system from DuctSox.


DuctSox, a fabric HVAC duct systems manufacturer, now offers SimpleSox™. According to the company, SimpleSox is the HVAC industry’s first field-adjustable, modular, configurable, and fully-stocked fabric duct air dispersion system for smaller, non-plan/specification ventilation applications. SimpleSox systems are simple to design, 40 to 80 percent quicker to install, and 25 percent less expensive than conventional metal duct/register systems, said the company.

The UL-approved SimpleSox consists of round 15-, 5-, and 1.5-foot modular lengths of white polyester-woven, non-porous fabric ranging in five diameters of 12, 16, 20, 24, and 28 inches that accommodate up to 6,000 cfm per run. The system’s versatility is based on the patented, two-foot-wide Adjustable Air Outlet (AAO), a four-orifice component that can be zippered anywhere into the duct run and offer a variety of throw distances, volume, and directional capabilities comparable to metal duct/register systems.

Supplementary components consist of an inlet collar, adjustable flow device (for turbulence), 90-degree elbow, and endcap that are fully stocked and available for same-day delivery from DuctSox’s North American manufacturers representative network, or next-day delivery via online or telephone ordering. Quick delivery makes SimpleSox a fast and reusable air comfort solution to emergency situations, temporary structures, and non-permanent installations.

KV Bracket is part of Duro Dyne’s Dyna-Tite product line.


Cable locks and wire rope have been sweeping the HVAC market as the newest and fastest way to secure ductwork and equipment. This method has been shown to reduce installation time and improve safety at the jobsite when compared to traditional hanging methods such as band iron, perforated strap, and threaded rod, said the company. Duro Dyne’s Dyna-Tite product line encompasses everything needed to successfully hang ductwork, including three different size cable locks with working loads up to 640 pounds, and a variety of accessories to accommodate virtually any application.

Duro Dyne’s latest breakthrough is the KV Bracket. The KV Bracket enhances the Dyna-Tite suspension system by the addition of an integral bracket, which fastens the cable lock to the duct with sheet metal screws. Once the KV bracket is attached to the duct, the wire rope “drop” is passed into the entry hole at the top of the bracket, through the cable lock, and out the exit hole at the bottom. The locking teeth inside the cable lock engage the wire rope and secure the ductwork in place.
