- Thumb operated latch opens the tool’s compound leverage handles and the jaws of a built-in wire cutter to easily sever the exposed wire rib coil of the duct liner
- Tie-tensioning mechanism to install a nylon tie strap and secure the flex duct take-off collar, use the wire cutter to trim the excess
- Trimming and installing flexible round duct is now as easy as one-two-three with Malco’s FDC3 multi-purpose tool.

While the overall design of the product is nice I’ve found certain flaws and quirks in the product.
1. the strap tool has no adjustments to it and will break the bands rather then tighten and snap them off
2. The blade is nice but you really need to make a cover of belt holster for it, otherwise its to dangerous a tool to be loose in a tool bag of box.
The Combination is great idea, but still needs work on certain sections
