manual Cleat benders

Cleat Folders are used for making HVAC sheet metal ductwork.

A Manual Cleat Bender is used in making ductwork, to form the Cleat on fabricated piece so Drive Cleat can be attached. The Cleatbender turns a flat edge 180 degrees to prepare it for the Drive Cleat. For each drive turn, there are three handle pulls: the top to start, the bottom handle to almost complete then release the starting position and the top handle again to finish off.

Duct before edge is turned Duct turned 180 degrees, hem on two sides. Drive Cleat

The drive cleat is used for anchoring two ducts together. In most instances, they will be used with top and bottom reinforcement of Flat “S” Cleat or Standing “S” Cleat.

The alternative to a manual cleat bender is a powered cleat bender.
