---------------------- multipart/alternative attachment Terry, The URL you sent has the clamp listed at $26.99. My thoughts are that the K body clamp has a built in plastic pad surface and it's wider to grab a larger surface area to prevent slipping. You wrote that it only cost $7 but the savings was $7 not the cost. The reach is greater on your clamp than the "k" body but the iron jaw could easily dig in the underside of the rim. I have 2) 12" clamps of the style you offer and like them a lot. They are very strong. I just thought that the extra pad protection was worth the effort of ordering the "K" bodies. I paid roughly the same for the same length clamp.
