Nordfab® A Comprehensive Guide to Ducting End Types
Summary
Nordfab® offers several end types for its Quick-Fit® duct components so they can connect to each other, existing ductwork, or machinery. Standard rolled edge ends pair with the QF clamp for quick assembly; flanged ends (Angle Flange or flat/custom hole pattern) adapt to existing flanged systems; RAWFLEX ends secure flexible hose connections; and "No Fit" is available for components that need no end customization. Choosing the right one depends on your existing system, connection points, and installation needs.

What Are Nordfab® Ducting End Types?
Nordfab® manufactures a full range of end types and styles to ensure Quick-Fit® duct components easily fit together, add to existing ductwork, or connect to machinery.
Rolled Edge (QF) Ends
Quick-Fit® products feature a rolled edge that integrates with the QF clamp to make ductwork installation quick and easy. The rolled edge end is standard on the majority of Nordfab® products. However, on custom component orders with more than one end style, you may require a QF rolled end specified separately.
Flanged Ends
Flanged ends allow Quick-Fit® ducting to adapt to existing flanged ductwork or machinery with flanged connections. Nordfab® Ducting offers industry-standard Angle Flanges, or flat flanges for individuals who require a custom hole pattern. Learn more about flanged Quick-Fit® components.
RAWFLEX Ends
If you're adding flexible hose into your ductwork, the RAWFLEX end has a bead around the duct component near the edge to help secure clamps placed around the hose.
No Fit
For components with no customization on the end, Nordfab® can provide "No Fit" (no fitting).

Key Considerations When Selecting Nordfab® End Styles
Each end style is engineered to meet specific installation requirements, ensuring that Nordfab® Ducting can be integrated into virtually any dust collection or air handling system. Our technical support team is available to help you select the most appropriate end styles for your particular application, ensuring optimal system performance and ease of installation.
When planning your ductwork system, consider the following factors to determine the best end style for each component:
• Existing system configuration
• Connection to machinery or other equipment
• Need for flexibility or future modifications
• Installation environment and accessibility
• Industry-specific requirements or standards
By offering this wide range of end styles, Nordfab® ensures that Quick-Fit® ducting systems can adapt to your unique needs, providing a versatile and efficient solution for dust collection and air handling applications across various industries.
FAQs: Ducting End Types
What end types does Nordfab® offer for Quick-Fit® ducting?
Nordfab® offers rolled edge (QF) ends, flanged ends (Angle Flange or flat/custom hole pattern), RAWFLEX ends for flexible hose connections, and "No Fit" for components that need no end customization.
What is a rolled edge end used for?
The rolled edge end integrates with the QF clamp for quick, easy ductwork assembly. It's standard on most Nordfab® products, though custom orders with multiple end styles may need it specified separately.
When should I use a flanged end instead of a rolled edge end?
Use a flanged end when you need to connect Quick-Fit® ducting to existing flanged ductwork or machinery. Nordfab® offers Angle Flanges as the industry-standard option, plus flat flanges for custom hole patterns.
What is a RAWFLEX end, and when do I need one?
A RAWFLEX end has a bead around the duct component near the edge, designed to help secure clamps placed around flexible hose when adding hose into your ductwork.
What does "No Fit" mean?
"No Fit" means no end fitting or customization is applied to that component — it's used when a duct part doesn't need a specific connection style on that end.
How do I decide which end style to use for my system?
Consider your existing system configuration, how the component connects to machinery or other equipment, whether you'll need flexibility for future modifications, your installation environment and accessibility, and any industry-specific requirements. Nordfab's technical support team can also help you choose.
Can I mix end styles on the same custom order?
Yes. Custom component orders can include more than one end style — for example, combining a rolled edge on one end with a flanged or RAWFLEX end on the other, depending on how the component needs to connect.
