Hybrid Worm Drive Clamp - 4"

13 Reviews


These stainless steel worm drive hose clamps conform to round or oval shaped dryer pipe and incorporate an exclusive hybrid combination 5/16” hex head, straight (-) and Phillips (+) offering three user friendly options for tightening.

Unlike the zinc coated steel clamps, the stainless steel offers a noticeably smoother operation with minimal binding as well as being rust prohibitive. The extended screw provides ample space for your hex head driver to easily encircle the screw head.

There are no other clamps on the market that offer the triple convenience of the screw-head and the smoothest operating stainless steel band, manufactured exclusively for the residential dryer connection. Additionally, this product is made in the USA. Works on semi-rigid aluminum flex, wire-bound foil flex and the newly popular DryerFlex. Also available to the trade in bulk packages of 20 pieces.

  • Diameter range: 3.5” to 4.75”
  • ½” wide 201 Stainless Steel band
  • Screw head: 5/16" hex, Phillips and straight slots

You'll need two of them in most cases.

Great clamp, seemed of better quality than the previous one I used. The screw seemed to tighten nice and smoothly.

Good heavy duty hose clamp. Better than those I have found in box stores or even my local hardware!

Beats What You Will Find in the Big Box Stores by a Mile

by Pat| 6/12/2013 12:00:00 am

I purchased two of this from a chain big box hardware store. Not to insult anyone, but to me, the hardware these stores sell is so inferior it's like certain Chinese manufacturers go out of there way to make really soft alloys. Needless to say, the two from the orange big box place did not "worm" as they are intended to do, and they were prone to stripping out. Not these babies from In-O-Vate. Excellent. Highly recommended. They work properly (they worm closes as intended) and the screws are not soft, thus do not strip with two turns of a screwdriver.

Best Ever

I am a dryer exhaust technician and I put about 6 clamps on dryers everyday. This particular clamp is the best I have seen and wish I didn't have so many of the other type or I would use this one exclusively. It is large enough for any dryer vent and easily installs and clamps down as strong as you want it to keeping the airflow in the duct.

Good product

Very smooth mechanism - like the hybrid combination for tightening.Took a while to tighten using the G.E. brand flex duct. However, I appreciated your recommendation of the GE duct, even though you don't carry it. You put the customer first over profit. In addition, your customer support is outstanding.

Great Clamp

This works very well with the DryerFlex vent hose! Easy to use too.

Great product

I'm not an expert, but these clamps tightened much more smoothly than the ones they replaced11

great, but watch for metal shavings

by GH| 6/22/2012 12:00:00 am

This product is easy to use and priced right. The only downside were metal shavings around the fasteners -- wear gloves just in case.

Great clamp; worked just like it should according to our installer.

Solid Clamp - Good Quality Control

by Zech| 4/9/2012 12:00:00 am

Very solid clamps, they worked great, tightened down as they should, and did not slip.

Time saver

by Greg Clark| 8/2/2011 12:00:00 am

These are the only clamps that i will use. They open up fully so that you can get it around the transistion duct before you connect it to the wall. Other clamps will not do that, plus the clamps will not vibrate loose. Small price to pay for the best clamps on the market.
