Best Fixed Clamps
I decided to buy these because the factory default Fixed Clamps on my Penta Premium 3600 stringer left marks on the strings. These are incredible with less pressure required. Definitely recommended.
Deluxe Diamond Dusted Universal Tennis Squash Badminton Clamp which has a 12mm or 12.20mm shaft dimension. The total height is 13cm, of which 7.50cm relates to the shaft and the teeth width is 40mm.
Please note that on 99% of occasions, stringing machines require the 12mm shaft.

I recently started having trouble with one of the Pro's Pro badminton clamps on my Premium Stringer 3600 in that the string kept breaking adjacent to the clamp. After 5 years use, I decided to replace the clamps rather than chase down some elusive problem, and I'm glad I did. The Deluxe Diamond Dusted clamps are a joy to use and operate smoothly with very little effort. Moreover, with five fingers and diamond dusting, the clamping pressure needed is less and hence less likelihood of string damage. For another £20 over the standard clamp price, you get a vastly superior clamp - very highly recommended!
I recommend this clamp - I replaced the old one on my machine with this one and it was worth it!
