70249 5 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

I have been upgrading my hosee clamps to tooless one's with Rocklers 4" keyed hose clamps. They didn't make 5"ones so I purchased these to upgrade the traditional ones. They work well but not as nice as the 4 inch Rockler keyed ones.

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.

These clamps work well and are easy to tighten by hand. However they could be a bit longer. I struggled to get them over 5 inch dust collection hose. Ultimately I was able to fully unscrew them and install after hose was attached to dust port.

These amazing clamps clamped amazingly well.

Spend a little more and get better clamps. Technically it is the size advertised, but it cannot adjust big enough to slide over pipes it's supposed to fit. Most hose clamp allow for widening to position, these do not. If you want them to work, get one size larger than you need. Also, flimsy. You get what you pay for. Spend a little more and get better clamps.
