POWERTEC 4 Inch Double Loop Hose Clamps for Dust Collection Hose and Dryer Vent Hose, Quick Release Spring Clamps for Dust Collector and Dust Collection Fittings, 2 pack (70195)

These clamps are definitely better quality than the clamps that come standard with some dust collection parts. The standard clamps often slip, skip teeth, or just break open when you try to get them tight. These clamps hold tightly, and are easy to operate with the thumbscrew.

It definitely fits and does the job. The turn key is fairly stiff and takes a good bit of effort to turn.

These are much better than screw-type hose clamps for slippery non-compressible joints, such as dryer ducting. They are easier to use and are tighter. However, such joints will still be a bit slippery, so if you are desperate enough to upgrade to these clamps, you might as well bit the bullet and get rigid ducting.

work great in close areas

I would recommend these hose clamps for anyone installing a desk collection system or planning on a professional desk collection system.They hold up very well and yet are easy to remove if you need to expand your desk I would recommend buying an extra bag to keep on hand as your shop needs become become necessary

Work great. They are not ķ to the coil pvc pipe though. They do stay tight.

Great price, easy to use, and unlike some other items on Amazon it actually fits the hose size it claims to.I will continue to buy these as I need more of them.

These clamps are certainly nice looking and easy to use, but don't compare in strength to regular 4" plumbing hose clamps. Hope they last.

quick connect for dust collector

Expensive for what it is, but they work great. The little rubber tips on the handles tend to slip off, so watch for that.

Easy to use and fasten securely.

Good buy
