Air Flow Products 720-1-000000-041005 End Boot 4x10x5

Product Description

The AIR FLOW PRODUCTS 720-1-000000-041005 is a 72 Series end boot designed for residential and light commercial HVAC duct systems. End boots serve as the transition fitting between a rectangular supply duct and a floor, wall, or ceiling register. This fitting carries a 4 x 10 x 5 inch size designation, meaning a 4 x 10 inch duct collar transitions to a 5 inch offset outlet. Licensed HVAC technicians and sheet metal installers select end boots based on duct size and register placement, making an exact size match critical before ordering.

This end boot is suited for new construction and replacement duct work in forced-air heating and cooling systems. It is sold as a single unit. The 72 Series designation identifies the product family within the AIR FLOW PRODUCTS line, and the 4 x 10 x 5 size makes it a common fit for standard residential supply runs terminating at floor or sidewall registers. Verify duct collar dimensions and register opening size on the job before pulling this part.

Installation Notes

End boots are installed by licensed HVAC technicians or qualified sheet metal workers as part of a supply duct system. Power down the air handler or furnace at the disconnect before working in the duct system. Secure the boot to the duct collar using sheet metal screws and seal all joints with UL 181-rated mastic or tape per local mechanical code requirements. Confirm register and duct dimensions match this fitting before installation - size mismatches cannot be corrected in the field.
