Wow, that was quick, thanks a lot. The ones you refer me to are not the same design but knowing they are called hold down clamps, will help locate them.Looked on Ebay UK and Amazon UK and done a quick UK Google can't locate them in UK. Anyone any ideas where I can get them?
Hi, no if you look at my posted picture number 2 you will see it only has one arm. The Lee Valley has 2 one at front and one at back.Take another look Pete.. I'm pretty sure those are the exact clamp you posted...
how ever, here is the Jorgensen version found in Amazon UK
Hi again, sorry I think you were right after all just seen a clearer picture and they seem pushed forward on the ratchet thingy, so looks as only one arm.
