Excellent Permanent Clamp

I recommend these clamps to anyone who needs to permanently clamp their 4" hose to an outlet, adapter, inlet, etc. They form a good tight seal and do not fall off once properly tightened down.^M
I would not recommend these type clamps for an application where you would be moving the hose to different tools or positions. Reason being, one you would have to get your screw driver or socket wrench out, and two because the wear and tear of the clamp tightening on the hose over and over again would eventually wear a hole in the hose.^M

Good Clamp for Fixed Hoses

Good quality clamp. Well made without sharp edges. Threads worked flawlessly. Dual ring securely attaches dust hose to any connection.^M

However, the bolt head sticks out about 2". This is not a problem on fixed position installations, but it is inconvenient for portable dust hoses. For the rare end connection that will be moved from machine to machine use the standard hose clamps with a low profile blue handle.

Hands Down - The Best Clamp

I read other reviews before purchasing this clamp and am really glad I did. What I like is that the wires make great contact between the ribs of the hose and screw down very tight. Later I purchased the flat band kind from a local store and agree that this wire type is much better. It's much beefier than I thought it would be. Definitely the best clamp I've come across.
