I need to source seat clamps in aluminium 28.6mm diameter.
They are not going to be used for their original purpose so I need to specify that the crew that clamps the item closed screws directly into the body of the clamp, not into a loose nut.

My preference is for the least intrusive/bulky option, it does not need to be strong, it just needs to clamp.

Colour options would be an added bonus but not essential.

I have attached a generic picture

I can supply more images, one from a unit I already have which is great, and two more that look like they would suit my purpose.

Also a picture shows the type that does NOT work for me where the screw tightens into a retained nut rather than the item itself.

Many thanks.
