The SNAPPY p5-606 is a galvanized steel straight register boot designed for residential and light commercial HVAC duct systems. This fitting connects round duct to a rectangular floor or ceiling register opening, allowing conditioned air to transition from round supply trunk or branch lines into a standard register box. The p5-606 features a 6-inch round collar inlet and a 6-inch x 10-inch rectangular outlet, making it a standard size for supply air distribution. HVAC sheet metal installers and duct fabricators are the primary trades working with this fitting.
This register boot is used in forced-air heating and cooling systems where round duct branch lines terminate at floor, ceiling, or sidewall register openings. The straight configuration suits installations where the duct run arrives perpendicular to the register face without requiring an offset or angle. It is commonly installed during new construction rough-in or duct replacement work in residential builds.
Designed as an OEM-style replacement or new-construction fitting for residential and light commercial forced-air duct systems using 6-inch round branch duct and standard 6-inch x 10-inch floor or ceiling register openings.
This fitting is installed by licensed HVAC technicians or sheet metal mechanics as part of supply duct rough-in or replacement. Secure the round collar to the branch duct using sheet metal screws and seal all joints with UL 181-rated foil tape or mastic sealant per local mechanical code requirements. Power down the air handler and close the system before cutting into existing ductwork. Do not overtighten screws on the galvanized collar, as deformation can affect duct seal integrity.
