These clamps worked for what I bought them for. I had in mind something with 5mm threaded lugs to take screws holding my WB but missed seeing what else VO can supply. But, being ‘handy’, I had a plan that worked out just fine! The result isn’t particularly aesthetically pleasing but fully practical for use!

Bottle Cage Clamp

Rebuilt a mid/late 80s Trek 510 frame. The seat tube lacked bottle bosses and I wanted to carry a second water bottle for long rides. These clamps worked well. Note that they lack padding or any protective layer. I applied a strip of electrical tape onto the metal clamps before installing so they wouldn't scratch or damage the frame. The clamps aren't particularly elegant but they're a decent, inexpensive, and easy-to-install solution.

A simple solution for a bike that lacks braze-ons. Might be nice if the clamps were rubber backed, reinforced at the bolt holes, and maybe had more length to accommodate oversized tubes, but it does its job well enough.

These clamps looked and worked great on my 1979 Centurion Elite. I also have a period bottle cage that made the whole package look factory. One thing I did before installing, was to put vinyl tape on the bottom of the bands, so they were softer on the down tube.
