Stop Cutting Tie Tails by Hand. The TY6 Does It Automatically.

Every HVAC installer who's ever balanced flex duct with one hand while trying to snip a cable tie tail with the other knows the problem. The Malco TY6 Flex Duct Tie Tensioning Tool eliminates that entirely. Set your desired tension with the finger-operated adjustment knob and squeeze the tool onto the tie. When the preset tension is reached the breakaway spring mechanism fires automatically, releasing the lower handle and engaging the blade to flush-cut the tail in one seamless motion. No second step. No snips. Done.

Protect the duct. Protect the job.

Over-tightening a cable tie on a flex duct collar crushes the inner lining and creates airflow restrictions that can cost you a callback. The TY6's adjustable tension knob lets you set a consistent, safe pull force for every single tie on the job. Set it once, and every connection gets the same secure, code-compliant result without guesswork.

Built for Professionals.

The TY6 is designed for HVAC installers. Hardened steel stampings, long-wearing internal components, and a weather-resistant nickel chrome finish deliver dependable performance in attics, crawlspaces, and mechanical rooms. The contoured vinyl cushion grips with hand stops and smooth lever action keep fatigue low even through the biggest installs.

Use Genuine Malco Ties for Consistent Results. The TY6 is designed to work seamlessly with Malco TY34 and TY48 nylon ties, giving HVAC installers dependable tension, secure hold strength, and clean automatic cut-off performance on every flex duct connection.

TENSION AND TRIM NO MANUAL CUTTING REQUIRED

The TY6's breakaway spring mechanism automatically releases the lower handle the instant your preset tension is achieved, engaging the blade to flush-cut the excess tie tail in the same motion. No fumbling on the collar while balancing flex duct overhead, just tension, cut, and move to the next one.

ADJUSTABLE TENSION KNOB SETS CONSISTENT PULL

The finger-operated adjustment knob lets you dial in the exact tension needed to secure flex duct to a take-off collar without over-tightening and crushing the duct lining. Set it once per job and every tie gets the same consistent pull, eliminating collapsed flex or failed connections.

 

HARDENED STEEL WITH NICKEL CHROME FINISH

Built for continuous on-the-job use, the TY6's hardened steel stampings and long-wearing internal parts are finished in a corrosion-resistant nickel chrome coating that holds up in attics, crawlspaces, and outdoor mechanical rooms. Designed and made for professional HVAC installers.

WORKS ON 125 LB AND 175 LB NYLON TIES:

The TY6 handles both standard 175 lb & 125 lb tensile strength without adjustment — making it the only tie tool you need for flex duct collars, bundle securing, and equipment tie-downs up to 15 inches in diameter. For best results on fiberglass flex duct, pair with Malco's adjustable nylon ties.
