POWERTEC 70250 6 Inch Key Hose Clamp, Thumb Screw Key Adjustable Stainless Steel Hose Clamps for Dust Collection, Dust Collector and Dryer Vent Hose, Pipe Clamp, RV Clamp, Worm Gear Clamp, 5 pack

6" too large for my dryer vent. 4" too small.Returned for 5 " size & works well.

Good quality, for nicely over a 6 inch duct hose. A bit thinner than normal. Typically clamps of this size are 1/2 inch (12.5mm), these were 3/8 inch (10mm). Not a huge deal for my application, but be aware of it if it matters for yours. I was a bit worried the plastic knobs would strip out before they tightened. I'm sure if you Mongo it hard enough, but I had no issue and they felt pretty solid.

Nice quality not too hard to use good value.

Clamps hoses, but the thumbscrews are too close to the hose to easily tighten. They should have extended further out and maybe been larger

I love the thumbscrew feature. I have a leaf vacuum for my lawn tractor and it will plug up. I can remove the 6” hose with no tools. Unplug it. And put it back quickly. Glad I bout it.

Great price!

I finally got right size my mistake. I use for vacuum bag . Works great.

too thin (minimal width of strap section is likely to end up cutting vinyl dust collector hose

This product was used for a 5" dryer insulated hose. It works great but need to use pliers to turn the thumb screws for the desired fit.

Works well

Très satisfait de ce lot de colliers POWERTEC. La qualité est au rendez-vous : l’acier inoxydable est robuste et ne montre aucun signe de rouille, même après utilisation dans un environnement plus humide. Le système à clé moletée est vraiment le gros plus. Pas besoin d’outil, on peut serrer et desserrer rapidement à la main, ce qui fait gagner du temps sur les installations ou les ajustements. Je les utilise principalement pour des conduits (ventilation / poussière), et le serrage est ferme, sans fuite ni jeu. La plage d’ajustement est parfaite pour du 6 pouces et reste bien en place une fois serré. 👉 Points forts : Construction solide en acier inoxydable Serrage rapide sans outil Bonne tenue et étanchéité Format pratique en lot de 5 Bref, un produit fiable et pratique que je recommande sans hésiter 👍

The fit was great and work as advertised

The butterfly tab, on this gear clamp, is obstructed by the tail of the clamp advancing while this same butterfly tab is being turned. If someone made a product, based on a picture, and then did not test it for functionality, this is exactly what happens. Another excellent example Of an inexpensive, foreign made product designed to use resources and materials, for production inputs, in such a way that their products quickly find their way into the landfill, thus completely wasting all the efforts that went into extracting those resources necessary to produce the product.
