2 Pack 4 inch Hose Clamp, Adjustable 3 1/2"-4 1/2" OD, Handle Screw

Used these to secure 4 inch hose to my tools for dust extraction. Worked great and tightened without issue. If you're using it for 4" hose with metal reinforcement I would size up a little to allow for the clamp to open more. These worked but took a little more effort than my bigger ones

These work great but from time to time they slip a little when tightening them up. This has not posed a problem for me just be aware. Once you give a fe more turns they grab again and cinch down well enough to secure the ducting to my diesel heater. Good product/value

Mechanism is high-quality and smooth when tightening.

One might argue it's hard to get a hose clamp wrong. But I like that these have wing nuts, which eliminates the need to use a screwdriver. They seem well-made and easy to use... and the price was right (more expensive would have put it in the same range as every other brand and it wouldn't have stood out as special). The price caught my attention, the quality satisfactory. So all in all, a good purchase.
