A flat shoe is a ductwork component used to connect sections of duct or to connect ductwork to other HVAC equipment. It features a flanged edge manufactured to the size of the parent spiral size, which provides a secure and stable connection between both ducts

Description:

Material: Manufactured from galvanized steel

Design: The curved shoe is a piece that is fixed directly onto spiral ductwork with a flange around its circumference. The spigot end of the curved shoe is “male” and will slip directly inside spiral ductwork. Curved shoes benefit from better performance that saddles due to it’s lead in edge

Uses in Ductwork Systems

• Connecting Duct Sections: Curved shoes are used to join two circualr sections of ductwork together, ensuring a tight and stable connection

• Attachment to Equipment: They connect ductwork to HVAC equipment like fans or kitchen canopies, providing a secure and airtight seal

• Sealing: Once fixed the flange should be sealed with duct sealant to create an airtight seal, improving the efficiency of the ductwork system and preventing air leaks

In summary, a curved shoe is an essential component in ductwork systems, used for creating secure, stable, and airtight connections between two circular duct sections
