Good Quality Key Clamps
Grandma here ... needed to revise the connections for the dryer vent. These key clamps make it easy to get the job done quickly and without tools. Good quality. They should last for years. The hardest part was getting behind the dryer!

Good clamps
I've found these clamps very useful in repairing dryer ducts for customers. They are more accessible for changeouts going forward. Also, by making hand tightening easier, they prevent over-tightening with powered tools.

Hose connectors, who needs them?
Geat little hose clamps. Hold really well on my 4inch dust collector flexible hose which goes to my tools. I may invest in the magnetic connectors next for quick swapping of my tools instead of using more blast gates.

Good hose clamps, well prices and no scavenger hunts in stores trying to find them
Great to have these always in the shop when needed, and cheaper than looking for them and getting them in the store when they are available

Very Good Closures
This past summer I installed a barn-wide dust collection system made from different types of 4" pipe. These clamps replace and are used ON ALL joints on that new system. So far, with 5 heavy duty machines a planer, bandsaw, lathe, table saw, and jointer all feeding into a single dust collector..... with on/off valves.... the clamps have all held, have remained in place and tight. I wouldn't use these clamps on something that has a lawn application because of the plastic 'nut.' Other than that, they are super.

Great product
Works good. So much easier than messing with a flat head screw driver. The worst kind out there. This is good. It works and put enough pressure to keep the dust collection hose tight
