Whenever your job calls for securing round flexible duct to outlets, pipes or fittings, you can do the job better, faster, and at a lower cost using DYN-O-TIES, flexible duct ties.

No tapes, no screws, no clamps. Position the flexible duct and slip a DYN-O-TIE around the flexible duct over the joint. Draw the DYN-O-TIE tight with our ratchet action hand tool. A push with the thumb completes the job by clipping off the excess nylon tab for the neatest and most secure connection you could want.
