Key Benefits
IHS gives facilities a practical performance upgrade over basic suspension methods.
- Cost-Effective Solution - A smart fit for budget-driven projects where performance matters, but advanced tensioning is not required.
- Quiet Operation – Internal hoops reduce fabric motion for steadier performance with less noise than metal ducts in occupied spaces.
- Consistent Shape Retention - IHS supports basic duct geometry and improves shape retention over simpler suspension approaches.
- Simple Installation - Single-row cable or track suspension keeps installation straightforward and efficient.
- Lightweight Alternative to Metal - Fabric construction reduces handling difficulty and structural burden compared to traditional metal ductwork.

Overview
Product Overview
IHS is a traditional fabric duct support and retention system that uses internal hoops to maintain duct shape during operation. Unlike engineered tensioning systems, IHS relies on simple internal structure and standard suspension to support consistent airflow and hold its shape. For teams that need more performance than a basic fabric duct cable system or fabric duct track system can provide, but do not need the added structure of SkeleCore tensioning systems, IHS fits that middle ground. -
How It Works
How It Works
- Internal hoops are spaced along duct to retain shape.
- Fabric is tensioned along top, typically at 12 o’clock position.
- System is suspended by cable or track.
This approach helps reduce motion during airflow and improves retention compared to simpler support methods. While it doesn’t have full-system engineered tensioning, IHS does help the internal hoop fabric duct keep a more stable form during operation.

Fabric and Material Options
IHS is available in multiple fabric types to match airflow, durability and environmental requirements. Material options include Sedona-XM™, Verona™, DuraTex™, Opti-X™ and TufTex™, giving designers and contractors flexibility to align your system with your unique application.
When to Choose IHS
Choose this internal hoop fabric duct system when your project calls for cost efficiency, and dependable performance with simple construction. It’s a strong fit when long-term durability and easy installation matter, without the need for advanced tensioning.
IHS works well in standard applications with minimal performance demands, especially where owners or contractors want a practical fabric duct solution that improves shape retention without stepping up to a more engineered tensioning system.
BOTTOM LINE: It’s the right choice when the priority is reliable everyday performance, not maximum structural control or premium aesthetics.
IHS vs. SkeleCore Systems
SkeleCore® systems sit above IHS in the DuctSox hierarchy of sophisticated solutions. They use engineered tensioning to deliver stronger shape retention, improved aesthetics and higher long-term performance in more demanding applications. Choose IHS when the application is straightforward and value-driven. Move into SkeleCore® when performance, appearance, diameter, or operating conditions demand more structural control.
