Universal Start Collar Back Pan


Just like the name, our Universal Start Collar Back Pan works with almost all air vent types. We wanted to make it easy for our customers to experience the best air flow quality. This back pan is:

  • Adaptable collars anywhere between 6” and 14”.
  • Made from durable materials 
  • Matches most interior themes and patterns
  • Need to purchase a Start collar from your local hardware store and install it into the backpan.

Our back pan is unique and suitable for any office space vent. No need to measure before you order! Boost your office space’s comfortability and IQA. 



Universal Start Collar Back pans are used when you are unsure of the neck size and to provide extra insulation, absorb noises, and are also used for fire safety regulations.


  • Powder-coated steel adds insulation and protection.
  • The fiberglass top is damage resistant – must be cut to the size of the duct and start collar.
  • The back pan is universal — no need to take measurements before ordering!

The Universal Start Collar Backpan by Comfort First Products is made from high-quality materials. The materials that we’ve used adapt to collars anywhere from 6” to 14”, providing a truly universal option. This collar back pan is especially ideal for buildings with wide ranges of start collars throughout. Once you’ve added the start collar to the universal back pan, you can then install your Comfort First Filtered Diffuser to the back pan.

You will need to purchase a start collar from a separate local HVAC supplier.
