TDF Corner:
The TDF (Transverse Duct Flange) Corner is a key component in the assembly of rectangular duct flanges. It is used to join flange frames at the corners, providing structural integrity and a secure connection. Typically made of galvanized steel, TDF corners ensure durability and compatibility with flange systems for HVAC ducts.

TDF Clip:
TDF Clips are used in TDF flange systems to fasten and secure duct connections. These clips lock the flange frame sections together, ensuring an airtight and stable connection. They are commonly used for quick assembly and disassembly of ductwork.

S-Clip:
The S-Clip is a simple and widely used connector for joining two sheets of metal ductwork. Its "S"-shaped profile allows it to slide over the edges of two duct panels, creating a snug and secure connection. It is especially useful in non-flanged duct systems for a quick and cost-effective connection.

Ductmate:
Ductmate is a brand name often associated with flange systems and duct accessories. It typically refers to a rectangular duct flange system that uses components like flanges, corners, gaskets, and clamps to create a strong and airtight connection between duct sections. Known for durability and efficiency, Ductmate products are widely used in commercial and industrial HVAC applications.

C-Clip:
The C-Clip is another type of fastener used in ductwork, designed to join and hold duct sections together. Its "C"-shaped profile makes it easy to install over duct edges, ensuring a firm and reliable connection. It is often used in various duct systems for quick assembly.
