Buying Guide

Key purchase considerations:

• Duct type compatibility: ductboard, sheet metal, and round or rectangular transitions require different collar designs and gauges.
• Gauge and durability: thicker gauges (e.g., 24–26) offer higher durability; lighter gauges (30) are easier to handle but may be less robust.
• Damper presence: dampers enable airflow control; choose stick-on or snap collars with dampers if zoning or balancing is needed.
• Flange design: tabbed/flanged collars provide secure attachment to duct surfaces; select based on whether you’re mounting to duct board or metal.
• Installation method: snap-tap, stick-on, or traditional start collars—consider time, tool availability, and surface preparation.
• Project scale: multiple collars or bundled options can reduce overall installation time and cost.

FAQ

1. What is a start collar used for in HVAC systems?

   Start collars create a secure entry point for duct connections, helping to anchor and align duct sections.

2. When should I choose a damper-enabled collar?

   Choose a damper collar when you need to regulate airflow or balance zones within the system.

3. Are thinner gauges acceptable for outdoor installations?

   Thinner gauges are generally less durable in outdoor conditions and may require protection or sealing.

4. What is the difference between a tabbed flange and a flat flange?

   A tabbed flange provides additional attachment points to duct surfaces, improving stability on duct boards or plenums.

5. How many collars might I need for a project?

   Count the number of joints and transitions; having a few extra collars can prevent delays during installation.

6. Can these collars fit both 16″ and other sizes?

   Most 16″ collars are designed specifically for 16″ ductwork; verify compatibility for other sizes before purchasing.
