Pro's Pro Swivel Clamp Base and Bar V2b problem

I bought these bases:
Pro's Pro Swivel Clamp Base and Bar V2b
to go with some pp clamps in the hope it would be smoother than the ones on my rab 1000.
I actually decided to keep my existing rails which are better than the ones supplied.
I'm finding it tricky to set up the clamp bases and lock. Is there a recommended way of doing this?

So there is a nut underneath and an allen key screw on top.
They locking ok but the levers on the top part are a bit floppy - I'm trying to set so a 90 degree turn locks and unlocks smoothly. Fiddling about I don't seem to be able to get the right balance between the nut/allen key for it to work correctly.
Appreciate any thoughts.

I'm intrigued by this, because I've had my RAB for 11 years. I've used a few Pros Pro machines in recent years when helping out some friends who have bought them, and my experience was that the quality of the clamps was night and day. To say I was unimpressed with the Pros Pro offering would be an understatement. What was wrong with your RAB clamps? And do you find the Pros Pro better? I'm also curious how old your machine is... whether your clamps had been worn out, or perhaps quality diminished in more recent years.

Regarding your question though, your link isn't working. Is the Allen key engaging but even when tightened it isn't enough? The immediate thought that occurs - assuming everything is installed correctly - is whether the thickness of the rails differs.

I was going to say as well, possibly the rails are different thickness since you kept the same rails and replaced the base clamps. Try and use the rails that came with the clamps.

I also see it that way, because I have already used some colleagues in the repair of the cheap and for me useless Pros Pro machines. Unfortunately, people always fall for the cheap price and think they have made a good choice when buying such junk. The many calls for help for these devices testify to this.
It is certain that one can cover Racquets conditionally, whether the quality corresponds however to the usual standard, I do not want to confirm.

The rab clamps seem to have got worse over time despite cleaning and the bases didn't seem snappy any more to me. The new pp clamps seem better
I'll check the rails later for diferences - the pp ones looked a rougher finish so I kept the rab ones but again I'll try one later. Regarding the choice - there doesn't seem to be any other options in the uk that will fit my machine.

@alexmcnab, I did pretty much exactly what you did.

I have a nearly 30 year old Eagnas clone Stringing machine with smooth rails. I decided to purchase some new Clamp Bases because the original ones just started to slip too much. (I purchased the machine second hand so who knows how many racquets have been strung on it over the years.)

After a bit of searching I concluded that the PP Clamp Bases would fit my machine. Problem was that the rails that come with the Clamp Bases were not compatible with my machine's turntable. Anyway, I ended buying the whole kit because I wanted the Clamp Bases and knew they would most likely be compatible with my existing Eagnas String Clamps.

The arrived, and sure enough they slotted into the existing rails. My existing String Clamps were compatible. (I also purchased a couple of PP String Clamps as a backup solution if my existing clamps didn't fit into the clamp bases chimneys.)

I had to tinker a bit with the nuts underneath and the allen screw on top to get the whole thing to look smoothly. On occasion on one clamp, the lever will start to get a little loose over time, but I simply tighten it with an allen key. It takes me about 1/3 of a turn to lock the clamp base. And as long as the rails, and the underside of the clamp bases are clean, I never have a problem with slipping.

Clean both the rails and the underside of the clamp bases regularly. I clean them after every 20 string jobs or so. I remove the rails from the machine, and bathe them in boiling hot water and dishwashing detergent for 20 minutes. Then scrub them with a nylon brush. Then wipe them down with paper towels till dry. Then a final clean with Isopropyl Alcohol. And then do the same thing with the actual clamp bases.
